Masks may be liberty-preserving alternative to mandatory vaccines or vax passports

There may be an alternative to mandatory vaccines and the inherent privacy and security concerns of either paper or electronic vaccine passports: allow people to opt out, but normalize the use of masks in densely populated, public, indoor settings when conditions suggest caution is demanded.

In the United States, this requirement should be tied directly to CDC reported rates of dangerous, communicable diseases with wastewater surveillance informing decisions. Medical research should be funded to track the effectiveness of masks against flu and anything else that’s feasible, not just COVID-19.

Ongoing investigation of the role aerosols—and inadequate ventilationplay in spreading common diseases demands equal attention and funding.

I, for one, would not return to an office as of May 2021 without a mask on my face if the space didn’t promise four to six air changes every hour or a fully vaccinated cohort of coworkers! This Wired story is a must read for those who’d like to understand the origins of medicine’s deeply flawed 5 μ myth defining “airborne” pathogens.

While our coronavirus memories are fresh, we owe it to future generations to prepare better for the next global outbreak. It is as inevitable as SARS-CoV-2 was. Fumbling our collective response, however, is not preordained.

We’ve learned a lot during the course of the coronavirus pandemic.

Ample real world evidence is now available suggesting that even simple homemade cloth coverings reduce the risk of infection from at least this one airborne virus. Flu also virtually disappeared during the 2020-21 season, though that could be as readily attributed to social distance and isolation as opposed to masks.

In the absence of the worldwide supply chain disruptions common early in this pandemic, more definitively effective surgical and N95 masks are easily obtained and affordable. Employers with public storefronts should have boxes of them deployed in the workplace in the same way food service companies provide gloves to their workers.

As with gloves and hairnets in restaurant kitchens, masks should be the immediate, hygienic response to entering the personal space of unknown persons with unknown vaccination status while any community is in the throes of an infectious agent.

Massachusetts’s governor is quoted in a May 7th Boston Globe opinion piece as saying, “some people have ‘very legitimate reasons to be nervous about a government-run program that’s going to put a shot in their arm.’” The same piece goes on to report, “Attorney General Maura Healey… this week repeated her call for public employees to be vaccinated as a condition of their jobs.”

Requiring every public employee in a customer facing position to wear a face mask at work unless s/he chooses to offer verifiable proof of vaccination seems like a cheap, simple, practical solution to me. As every scientifically literate, law-abiding citizen of the United States now knows, wearing a mask is no more difficult* than wearing pants.

Rome, the power house of the ancient world, believed trousers were ridiculous, barbaric garments. Quite literally, Romans, like the Greeks before them, saw pants as uncivilized clothing fit only for uncouth Goths and Vandals. The entire Western world, and most people around the globe, now don trousers without compunction. Masking one’s face requires no greater degree of adaptation!

Most of us could decide which we prefer at work: to wear a mask, or to accept vaccination. Crucially, the public at large ends up protected either way.Redacted official CDC COVID-19 Vaccination Record Card

I think it is likely that I, personally, will never want to fly again without a face covering, if only because I’m so well aware of my own tendency to touch my face and even bite my nails when experiencing anxiety. It’s a terrible habit I’ve never been able to break, but a comfortable face shield or mask would remove almost all of that risk to my health.

There will always be liars and attempted cheats, of course. Responses to those caught committing public health fraud should be proportionate and focused on preventing harm to the community.

Perhaps being fitted with a device designed like the ankle bracelets employed for house arrest for a period of time would work, offering a visible warning to strangers while broadcasting via Bluetooth? a message alerting those in the vicinity of the need to increase social distance. This could be a system that works with individual’s cell phones, or a device required for public occupancy of spaces meeting certain size or density limits rather like the requirement to install smoke alarms and fire sprinklers before opening a hotel or nightclub for business.

The primary solution is to normalize the continued use of masks in dense situations where we crowd together with unknown persons. The secondary need is for public spaces to meet reasonable, updated standards for safety in light of our current understanding of risk in the post-COVID-19 world.

Once COVID-19 vaccines are fully approved by the FDA, I do believe that employees who work specifically with the most vulnerable population should be required to accept vaccination or leave those particular roles.

Aides in nursing homes should not be able to opt out of coronavirus vaccines, nor the flu vaccine in normal years, nor should nurses serving the immune-compromised. Prison guards—who work with populations literally unable to escape from unvaccinated sources of exposure—are another obvious group whose personal choices should not be allowed to endanger the lives or health of others.

The actual conditions of employment for such positions demand a workforce that doesn’t subject other people to unnecessary risk so easily mitigated by inoculation. Case in point: the unvaccinated Kentucky health care worker who caused the death of three elderly residents of the nursing home where s/he worked. To pretend otherwise makes a mockery of both human decency and common sense.

In another example: a recent study published in JAMA showed that 46% of organ transplant patients produced zero antibodies after a complete 2 shot course of SARS-CoV-2 mRNA vaccine. It’s unreasonable that such individuals should be unknowingly subjected to the ministrations—however well-intentioned—of unvaccinated health care workers, certainly not without the immune-compromised patient’s being informed of their relative risk and given the opportunity to offer fully informed consent to taking said risk.

Face masks could also offer an effective solution for the conflict between public school vaccination requirements and anti-vaxxer parents currently allowed in some states to claim religious or other non-medical exemptions for their children.

Further research might prove that masks are not effective against every disease against which we have mandatory childhood vaccinations, but face coverings could potentially eliminate the friction between parent choice and community health in the context of the vital public good which is free, universal education.

Where freedom is the prize—and outbreaks of vaccine-preventable childhood infectious disease remain rare in America—I’d argue that the value of face masks as an alternative to mandatory injections is well worth exploring.Disposable surgical mask

Western medical science was patently wrong, before COVID-19, when it declaimed that face coverings offered no protection from infectious disease. We still aren’t sure if they protect the wearer so much as those in the vicinity of a masked, sick individual, but we do have substantial evidence that widespread adoption of masks can protect populations during a deadly outbreak.

Perhaps most importantly, where even the most well-vetted, safest vaccine or medication carries some tiny risk of harm to its recipient, wearing an appropriate, well-fitting mask correctly has virtually zero chance of injuring anyone. Low cost interventions with few side effects are ideal public health measures.

Asian nations which had internalized the historical lessons of earlier epidemics had it right; many** normalized face coverings during flu season. Now we know better, too. Science proves its inherent value when we incorporate new data into our body of knowledge, especially when we recognize data challenging existing beliefs and ingrained patterns of behavior.

This BMJ editorial (PDF) highlights the danger of clinging to false understandings. This opinion piece by Dr. Zeynep Tufekci is well worth a read on the subject of organizations lurching only slowly toward acceptance of new information challenging medical and scientific preconceptions.

Before the next pandemic, we should take great pains to study when, where, and how cheap, medically risk-free facial coverings work to effectively control the spread of disease. How many thousands fewer would have died if we’d deployed masks as a solution worldwide in days instead of months in 2020?

This is not merely a political issue. It is a matter of public health. Where solutions exist that preserve both life and liberty, we owe it to democracy—and humanity—to explore every possible compromise.

Per the CDC, roughly 1000 flu cases were diagnosed during the pandemic 2020-21 season vs. more than 65,000 cases in the more typical 2019-20 season.

* As with trousers, some are the wrong size, and some are more comfortable on a particular body than others. Trial and error may be required to find the perfect fit for a given individual. Compared with the effort necessary to remediate infecting a susceptible individual with a life-threatening disease, this process is, at worst, a trivial inconvenience.

Per the Boston Globe: One of the major senior care operators in the state of Massachusetts came to a similar conclusion before COVID-19, though the quote perversely suggests that the organization was more interested in shaming staff members as opposed to protecting elderly residents:

“A year before the pandemic, Hebrew SeniorLife required flu shots for the first time for staff. Administrators achieved 100 percent compliance by imposing what seemed at the time an onerous condition: Holdouts would be required to wear masks 24/7 during flu season.

‘That was totally embarrassing then, but not now,” Woolf said. “We don’t have that hammer anymore.’”

In my opinion, after legitimate scientific studies were conducted to confirm that mask use by unvaccinated staff protects vulnerable patients to an equivalent level as vaccinated staff with faces uncovered, this could be a sufficient and highly appropriate alternative to mandatory shots in some cases.

Voluntary residential situations for children under age 18 should probably be held to a higher standard, in my opinion, and strictly require vaccinations for all but medically exempt participants. Absent direct parental supervision, it seems unreasonable to subject anyone else’s child to unnecessary risk due to personal choices that contradict the best current medical advice.

** Routine wearing of masks was imported to Japan from Western nations who’d adopted them as one response to the influenza pandemic of 1918-19. Unlike we Americans, Japanese culture never dropped them as a reasonable personal response to being contagious after the urgency of the Great Influenza subsided.

This Huffington Post article suggests that the Chinese adopted protective face coverings even earlier: “In 1910 and 1911, citizens were encouraged to wear masks to combat the pneumonic plague outbreak in Manchuria.”

The article goes on to point out that other Asian nations picked up the habit of covering faces during outbreaks due specifically to the SARS epidemic of 2002-2003. I’ve read that Koreans, in particular, actually viewed masks in a somewhat negative light as a foreign, Japanese import before the first SARS crisis.

DuoLingo rank in top 3% explains how I passed pandemic time

Perhaps because the pandemic gave me fewer distractions, I stuck with DuoLingo for most of 2020, primarily studying German and Spanish this time. I practiced there more than ever before, and I earned my longest continuing streaks.

I believe I created my DuoLingo account sometime during DS1‘s first year of home schooling, which would put that half a dozen years ago or so. My history with the platform is therefore fairly long, but my use has been sporadic. I come and go with all of my language studies, often in preparation for a trip, but I also use Pimsleur tapes and other resources, and I jump around between languages including those I started in school (Spanish, German, Japanese) but also occasionally French, Russian, or any other language I’ll be encountering in my travels.

Books foreign language learningI’ve tended to view DuoLingo as a game, a dabble, or a linguistic lark. I’m already on record on this point: I am a dilettante.

According to the 2020 Year in Review report Duo sent me this December, I ended up in this year’s top 3% of users. Who would’ve thought it? Yay, me!

DuoLingo 2020 Year in Review analysis

Whether these reports are a new feature, or if I’ve simply been “inactive” by winter in the past, this is the first time I remember receiving such a summary.

2597 minutes of language learning only averages out to about 7 minutes per day, roughly 50 minutes per week, so my minor obsession with the platform over the summer wasn’t too pathological. Nor is such a commitment sufficient, really, for anything except a nifty end-of-year ranking worthy of a self-congratulatory blog post.

Am I great at German now? Na ja, I’m afraid I still require subtitles to watch Nailed It! Germany or Dark on Netflix. Fluent, I ain’t!

Then again, the power of spaced repetition for retaining knowledge is undeniable. I’m hardly fluent in any language but my first, yet I have certainly cemented additional vocabulary in German and Spanish in 2020.

DuoLingo’s tag line is something like: “Learn a language in just 15 minutes per day.”

Analog wall clock showing 12:06The reality is that few will actually commit to the process, and almost no one can achieve fluency using any single tool. Even if you do commit 15 minutes per day to DuoLingo, you’ll be unlikely to be ready to address the United Nations without a whole lot of “something else” under your belt.

Also, the CEO is the person who invented CAPTCHAs, so there’s that working against DuoLingo’s place in my heart, too. I despise those stupid things.

Screen grab from DuoLingo showing 129-day streak achievementMany of us are susceptible to game-ification, however, so I encourage langauge learners to give DuoLingo a try. Extrinsic motivation isn’t such a bad thing for a necessary—yet repetitive—task like vocabulary study. I jealously guard my months’ long streak of continuous* days’ use of the platform. No stack of flash cards has ever kept me on track so continuously; not even the fear of low grades in college courses was as compelling as hoarding an imaginary currency called Lingots.

I’m 21 topics away from completing Level One of every available topic in German, the language I study most often on the platform. I’ll earn a completely meaningless Achievement dubbed “Conqueror” when I make it to that lofty(?) goal.

I’ve only topped out at Level Five on a single topic, Basics1 before the castle icon indicating Checkpoint One. It’s interesting, actually, recognizing from perusing the DuoLingo chat boards how some of us approach a language breadth-first, whilst others prefer a deeper dive, completing each topic up to its max in turn before moving on to the next.

I suppose the choice to do otherwise feels as obvious to other learners as mine does to me!

German has five Checkpoints or collections of topics, whereas Spanish has seven. Some languages are more popular than others, and the platform seems to offer more content for the languages users demand. Rational of them, I suppose.DuoLingo screen shot showing one more Topic to complete before Checkpoint 3 Castle is reached

I’m just shy of Checkpoint Three en español.

DuoLingo is free, so it is well worth its price. Ads are a significant annoyance when using the iOS app, but I don’t see any in the web version running on my desktop though I do employ multiple ad blockers.

The number of ads shown seemed to increase with total usage on the iOS app; I might not have kept up with it if I’d seen ads after every lesson from the beginning like I do now.

It’s worth noting that the ads in the app occur only at the end of each topic lesson, so I can and do cover my screen with my hand until the close button becomes available, and unwanted screeching video noise pollution can be silenced when it does occur. Moderately annoying still ads outnumber intensely annoying video ads on DuoLingo in my experience, but the ads to which you will be subjected are no doubt dictated by some algorithm outside my ability to predict on your behalf.Calculation of 41 weeks + 3 days times minutes per day = 417,600 minutes

I appreciate DuoLingo’s year end report for an accounting of how I spent 2597 minutes of pandemic isolation. Now if only I had such complete records for the other 415,003 minutes of it. I have some doubt that the balance was spent in so edifying a manner!

* Full disclosure: I have used a “Streak Freeze” save at least twice, so my current 129 day streak is somewhat less impressive than it looks.

FYI French has nine, Russian has five, and Hebrew has seven. You’ll have to do the resources yourself for any of the other 32 languages available to English speakers that are not in my DuoLingo queue.

Prioritize time with friends if you value your health

Do you prioritize your friendships?

Studies show—and common sense should confirm—that lives are healthier and happier when they include regular time spent in agreeable company. Getting together for coffee with a friend is as worthwhile an endeavor as hitting the gym or having your annual physical with the doctor.Espresso in demitasse cup on cafe table

“[R]esearchers have predicted that loneliness will reach epidemic proportions by 2030 unless action is taken”

and

“Current evidence indicates that heightened risk for mortality from a lack of social relationships is greater than that from obesity”

Quotes from a 2015 Meta analysis of research on loneliness/social isolation and its effect on health by Julianne Holt-Lunstad, et. al.

Yet, somehow, our culture presses us to “make time” for work (primarily) as if time can be spun from willpower alone and also lionizes those whose sexual relationships fit an idealized mold. Subsequent emphasis is then given to the familial obligations that result when offspring commonly results from the latter.

Woman hugs childTo the exclusion of all else, the role of spouse and, maybe, parent, especially if you’re a woman is presumed to offer all the emotional support one person needs, tacitly proclaiming romantic love* a panacea for every type of companionship.

Unfortunately, that notion is tragically flawed, placing outrageous pressure on one person to be “everything” to another when that is neither probable nor healthy. It kills marriages, leaving lonely people feeling like failures when they’ve followed the common wisdom and left their friendships behind after coupling.

Human beings are social creatures. We evolved to live in communities.

I’ve got it easier than most as chronic illness forces me to confront my limitations on a regular basis. If I wasn’t skilled at aligning my actions to my values before I got sick, having my physical energies truncated again and againand again so repeatedly has brought my focus to the point.

It’s a fine, sharp point, too!

Men, in particular, may literally be dying from loneliness, though social isolation is increasing for all genders. “Social” media is simply not sufficient to nurture human health and happiness.

People seated in beneath stone arches in Barcelona restaurantThough, by all means, keep reading my blog.

Call a friend. Make a date. Visit the pub. Take time to play a game together. Put it in your calendar, and prioritize it! Your other successes will mean very little if you go early to your grave for want of meaningful companionship.

College cheats: getting in is nothing; learning is everything

The most obvious truth revealed by the recent college admissions cheating scandal that has ensnared Hollywood celebrities and other rich fools nationwide is that typical Americans have completely lost sight of the purpose or value of education.

Paying bribes to be admitted to university is frankly moronic for most of us. All of the real value of the college experience comes as a direct result of studying—and learningtherein.

Graduation cap and degree captioned University of DeceitRich kids will continue to stumble into lucrative careers because they have the right connections. Average kids, and the less well prepared, will take on massive debt for less and less substantive rewards when we devalue our universities by sending kids with no direction or purpose simply to fill seats.

Naturally, those who steal and cheat to get into college go on to cheat while attending college. I wouldn’t want to work with or hire that kid!

Businesses already decry the lack of qualified applicants for job vacancies though the percentage of Americans attending college has been increasing for decades. Being admitted to college confers zero qualifications. Learning—at a university or anywhere else—actually builds skills.

So, too, does honoring oneself and one’s community by behaving with honesty and dignity.

True scholarship also enhances one’s life in less quantifiable ways. The cheaters are too cowardly to risk realizing this fact for themselves.

Pile of moneyEarning a college degree has held, thus far, as a predictor of higher pay, but for how long? When students are enrolled only because “college is the next step after high school” vs. following an interest in deeper, more focused study of something specific, the automatic pay bump for a bachelor’s degree will disappear.

We ought not mold our colleges and universities into the image of our less and less functional compulsory K-12 system. Academia is not the right fit for everyone. All students are not the same. Disparate careers benefit from differing methods of preparation for new workers. Human beings have different learning styles.

Jobs go to people who can do the tasks required. College, in and of itself, teaches no specific skill save mastering the “admissions game.” That’s defined as test taking and/or bribery and fraud, apparently.

Children should be encouraged to do their best academically, but honor their unique selves by accepting both their strengths and weaknesses. Don’t let them fall victim to the patently false modern myth that admission to “the right college” is a golden ticket to happiness, prosperity, or success.

Consider trade schools, sampling classes at a local community college, internships, or self-directed online study if there is no perfect path to a four year degree right after high school.

Life is so rarely perfect! Why would one person’s education be?

One of the most compelling stories by an alumna of the small women’s liberal arts college I personally attended came from someone who went on to attain an MBA from an elite American business school. This woman was committed to attending that particular institution for her advanced degree, but had to apply three times before she was finally accepted. They were eventually persuaded by her passion and dedication.

Her message to us: persevere when you know what you want. This particular woman of color had reached her own definition of personal success by working hard and refusing to take no for an answer. She was a CFO at a startup at that time.

Education is not a zero sum game, though seats at a particular university may be. Focus on attaining the skills required by a career suited to your personality and strengths, and do realize that “where you went to college” becomes irrelevant very quickly after graduation for the vast majority of people.

“Steal,” yes, because cheaters have taken, through fraud, a slot at an institution where another scholar might benefit and contribute honestly to the campus experience for the entire community.

Considering antidepressant medication? Try vitamin B-12 first.

This isn’t medical advice. I’m not qualified* to offer that.

Vitamin bottle B12 - 1I am simply a self-educated consumer who lives with a chronic health condition. I’ve drawn my own conclusions from research done as an intelligent lay person, tempering it with common sense. I invite you to do the same.

Many of us diagnosed with autoimmune conditions, degenerative neurological diseases, and chronic pain will be prescribed antidepressants. There are fine reasons for this.

Some chronic pain responds positively to antidepressant medications. Given in lower doses than those prescribed for psychological reasons, side effects are often less as well.

Here’s a link to a (long, almost 2 hrs!) YouTube presentation by Dr. Dan Clauw, M.D. that offers a great explanation for the current understanding of why these drugs may help certain types of pain.

Depression is also a normal human response to learning you can expect to spend the rest of your life with constant pain or in a rapidly degenerating physical condition.

That is a depressing situation for any rational person to contemplate. Treating mental health problems is important, and I do not sit in judgement of anyone who takes pharmacological steps toward better self care.

If you are a danger to yourself, please seek immediate, aggressive care. Do whatever it takes to get well. Your life matters.

That said, I’ve recently learned that the major physical symptoms of depression mirror almost exactly those of a vitamin B-12 deficiency. Hmm…

Even patients with valid diagnoses of other conditions—here’s a study about multiple sclerosis, for example—often have other stuff going on in the body that can make symptoms worse. Large numbers of hospitalized, depressed patients have measurable Vitamin B-12 deficiencies.

It isn’t known yet whether B vitamin deficiencies help create conditions that allow us to develop disease, result from lifestyle responses to living with chronic illness, or are direct side effects/symptoms of disease processes.

I’d argue that the underlying mechanism doesn’t matter so much when we’re talking about supplementing with vitamin B-12.

Why? There is no known upper tolerable limit for safety for supplemental B-12. Say that in plain English? No one ever “overdosed” on this vitamin.

Here’s a link to a more reputable (than me) resource, a state university, for detailed mainstream medical information on the subject of Vitamin B-12. And another to a US government fact sheet on the vitamin for American consumers.

B-12 is water soluble. If you take too much to be used by your body, it will leave your system naturally via your urine. You might “waste” the vitamins you’ve bought and paid for, but odds are tiny** that they will hurt you in any appreciable way.

If someone is ready to prescribe antidepressants to a patient, that patient must have at least one medical doctor who could also be consulted about taking vitamin supplements. Ask your doctor before starting a new treatment, including Vitamin B-12, but, odds are, you will be told this is safe to try.

You may also hear that vitamin B-12 won’t help you. But, then again, antidepressants aren’t a guarantee either. They include a long list of side effects, some of which are very unpleasant. Those prescription pills can also be expensive.

Also, it’s just as unscientific to assume the vitamins won’t help you as to assume that they will.

I’ve come to realize that no one cares as much about my health outcomes as I myself do. With good insurance and caring doctors, I’m still left with unanswered questions and a merely tentative diagnosis for what causes my chronic pain and fatigue. Where stakes are low and scientific certainty is lacking, I choose to perform nutritional experiments upon myself.

If it is highly unlikely to hurt you, and it could help you, why not take some extra vitamins for a while and see if you feel better, too?

Assuming your doctor said such a trial is safe, the only possible barrier is cost.

I picked up a bottle of store brand vitamin B-12 at wholesale giant Costco with 300 pills for $19. Each offered thousands of percent (20,833%) of the RDA***, making a bottle good for the better part of a year taking one per day.

That works out to $23.12 annually. Costco typically offers very good value.

At an expensive local vitamin specialty retailer, a three month supply (of 16,667% RDA pills) cost $16, coming out to about $64 per year. I suspect it would be hard to spend much more than this for these vitamins.

vitamin-bottle-b12-2.jpgThere are several forms of B-12 available, and both of these offerings are for the most expensive type, Methylcobalamin.

Some users have reported that the most common, cheaper form, Cyanocobalamin, doesn’t resolve their symptoms, but the Methylcobalamin form does. At less than $20 per bottle, it seems within financial reach of most Americans to do this self experiment with the potentially most effective version of the supplement.

My two sample bottles also both contain dissolving lozenges to be held under the tongue rather than swallowed and processed through the digestive system. Again, some argue that a sublingual or injected B-12 is more effective than a swallowed dose. I went out of my way to test this type of supplement, just in case, though science tends to think it is irrelevant for most.

In all of this, note that my primary interest is in clinical results, i.e., how I feel. It will be great if research comes to understand why and how B-12 or any other supplement improves patient outcomes. But I am not a working scientist.

The bottom line for how I make a decision about self-treatment comes down to whether or not I feel better, and at what risk.

The “clinically small” improvement of a group of MS study participants quoted above may be of only slight statistical significance, but when your function or your sense of well being has descended to, say, 25% of your old normal, well, then, 27% or 30% represents a win.

I don’t know what you should do to help yourself live a healthier life. I do have some opinions about which alternative health practices represent good risks worth a try for a person in pain. Perhaps this little experiment can ease some of yours, too.

Your body; your choices. Make them in good health.

*My education in both Biology and Chemistry ended in high school as my college science classes were limited to Physics courses. My major was Mathematical & Physical Sciences with a concentration in Computer Science.

Make no mistake that the side effects can be significant, however. They are also likely to affect your offspring, not just yourself. There are studies showing this in very obvious and less direct ways.

Powerful drugs are appropriate to treat significant illness, but I’d argue that they should be employed after milder alternatives have been tried and found insufficient.

Other sources, regarding. depression.and .neurological and psychiatric disorders

**There are some instances of allergic reactions to vitamin B-12, but I only read of such response to injections (shots), not over the counter vitamin pills. Reports of acne or skin rash in response to large dose vitamin pills do occur with some regularity.

You decide whether temporary skin issues are something that would stop you trying a larger dose of this vitamin for yourself.

***In most cases, we do NOT know the “optimal” level of vitamin intake. Vitamin B-12 reference ranges vary from 180-914 ng/L in the USA, 135-650 pmol/L (183-881 pg/mL) in Australia, and 500 – 1300 pg/mL. (ng/L=pg/mL, so no conversion necessary there.)

If you think this is an important thing for people to know, write to your government representatives and tell them you support basic nutrition research. Private companies have very little motivation to pay for this kind of work; there’s no resulting drug patent to fund the endeavor.

There’s a reason some public services, like infrastructure and basic research, are paid for by taxation. Otherwise, they simply aren’t available to all of us.
