Achieve New Year’s resolution to reduce stress at your work-desk
With the page turned over to 2020, office-workers worldwide must bear down again and do even better than ever before. If you did really well in last year, that just raises expectations for a similar improvement over the next 12 months. Naturally stress levels rise and performance drops off into a downward spiral. But, no worries, a solution is at hand: Simply pick up a small plant, preferably fool-proof such as these fine fifteen recommended by House Beautiful. Then, per a study by Japanese scientists*, whenever you feel worn down, take a 3 minute break to gaze at your plant and, when needed, care for it. Based on the results from experiments on over 60 participants, you will become more relaxed (as measured by pulse rate) and relieved of anxiety (based on scoring).
“Nature can serve as an antidote to over-stimulation or “attention fatigue,” as well as boost cognitive performance.”
Cory Steig, Health and Wellness Reporter, Make It, CNBC, 3/3/20, “This 3-minute, $3 habit could lower your stress and anxiety at work”.
It works for me. In any case, happy New Year! Don’t let the stress get to you.

Testing the adage that if you drink beer before wine then you will feel fine
Just in time for the partying hearty for Christmas today, my son-in-law Ryan, a chemist with 3M, alerted me to a statistical study published after last year’s holiday season by the The American Journal of Clinical Nutrition that questioned the advice of grape or grain but never the twain. Naturally, being a drinker of these undistilled alcoholic beverages, I wondered if my tendency to drink beer before dinner and wine for the meal would pass the test. But being a wonk for design of experiments, I was most curious to see a randomized controlled multiarm matched-triplet crossover trial—pictured below for this experiment on the order of addition for beer and/or wine.
Based on results from 90 participants, including a control group, “neither type nor order of consumed alcoholic beverages significantly affected hangover intensity (P > 0.05)”. What really mattered was the total consumption, although, interestingly, hangover intensity did not correlate to breath alcohol concentration (BrAC). However, the authors warn that
“The fact that we did not find a direct correlation between maximal BrAC and hangover intensity should not be misinterpreted as an invitation to drink until the cows come home. Likely, this correlation overall does exist but is not directly apparent in the narrow range of peak alcohol levels studied here.”
It’s disclosed at the end that Carlsberg provided the beer (premium Pilsner lager recipe from 1847) free of charge “for the sole purpose of utilization in this study”. Although I trust the author’s disclaimer of any bias, perhaps further study is warranted with stronger beers such as a Belgian trippel. Maybe wine would then be best drunk first. To be continued…
Prize-winning research only scratches the surface
Just in time for the super-dry, winter season, when us Minnesotans become terribly itchy if we do not diligently apply moisturizer, the Annals of Improbable Research awarded their 2019 Ig Nobel Peace (ha ha) Prize to researchers who discovered that people enjoy scratching their ankles. While one might get pleasure initially from giving in to an itch elsewhere, the satisfaction soon fades. But ankles do not rankle when it comes to scratching.
For all the details from the team of authors, including the Director of the Miami Itch Center, Gil Yoispovitch (italics mine), click this NIH Public Access posting of The Pleasurability of Scratching an Itch: A Psychophysical and Topographical Assessment.
Money buys happiness unless you get caught up in the Easterlin paradox
Posted by mark in Uncategorized, Wellness on April 23, 2019
The March 23rd issue of The Economist provides an interesting graphic on GDP per person—a measure of wealth—versus self-reported happiness. Overall it shows an upward trend that increases life satisfaction by 0.7 points (on a 10-point scale) as GDP doubles.
China is a prime example of money buying more happiness. Sadly, us citizens of the USA (and many European countries) are subject to the Easterlin paradox, which puts a limit on how satisfied people get as their income rises, beyond which money cannot buy more happiness.
Check out this interactive online version of the happiness vs wealth posted by The Economist. There, if American, you will see with some satisfaction (misery liking company) that Netherlands and several other wealthy countries share our downward trend. However, Germany and Britain remain on the upswing. (I wonder with Britain now in the throes of Brexit if their GDP will shrink and, if so, suspect that their happiness will also fall off.)
So, bottom line, for those of us stuck in the paradox, would you rather be richer or happier? That is a tough question!
A blog about blob
“Americans are getting fatter…and shorter” said the headline in the Venice Florida Gondolier Sun last month. The fatter bit was easy to swallow (ha ha), but the second part of this news–the lessening heights–caught me short (yeah, another bad pun).
Here are the average body measures for 2016 gleaned by the Gondolier Sun (Bob Mudge) from this just-released survey by the Department of Health & Human Services (HHS):
- Men 5 feet 9 inches, 197.8 pounds, 40.3 inch waist
- Women 5 feet 3.6 inches, 170.5 pounds, 38.7 inch waist
Mudge reported that the average man is four-tenths of an inch shorter than in 2006. At this rate I figure that men will be reduced to the size of a mouse by the year 3716.
Meanwhile, the New York Times (Nicholas Bakalar) noted that men have gained 8 pounds since 2002. Doing my math on weights projected to 3716 I calculate a massive 1170 pounds for these future mouse-sized men. That is dense (as are my projections)!
My frivolous extrapolations notwithstanding, the realities of actual measurements by HHS are harsh. Is it too late for New Year’s resolutions? If not, I am working on increasing my height in 2019.
“People tend to overreport their height and underreport their weight.”

Dream come true: Homework banned and school days delayed
The Wall Street Journal this week reports that, for the sake of “student wellness”, school districts across the USA are now banning homework [1].
The U.S. Department of Education figures that, on average, high-school students (those without the “get of jail free” card) spend about 8 hours per week on extracurricular assignments. Girls spend an hour more than the norm and boys an hour less, thus there’s a two-hour gender gap on homework. (You be the judge as to what this implies on relative intelligence. I don’t dare!)
Naturally, parents with ambitions for their son or daughter do not favor this trend to relieve academic pressure. Many evidently move their child to private schools that load on several more hours of homework every week. That would be a blow—being yanked away from all your friends at Easy Street High.
It would be worth it if more homework leads to a significantly better education. WSJ suggests that this may not be so for elementary students. That seems sensible. But what about high school? The author of The Battle Over Homework, Duke professor Harris Cooper, says that studies show a positive correlation of homework with achievement [2]. He advises that high-schoolers put in at least 90 minutes a night but beyond 2.5 hours the returns diminish (and any chance of a social life).
Meantime, other school districts, perhaps some that ban homework (that would be double dope!), have moved back their start times to provide more sleep for students. For the heads up, see these Shots from the December 12th NPR Health News on Sleepless No More In Seattle.
I can only say that my quarter of 8 am organic chemistry as a freshman at university did not go well. My notes provided a record of frequent nodding off by my pen trailing off every few lines. That was before I discovered coffee and became addicted to rising early.
Are you seeing red sorting out how much sunscreen to apply and at what strength?
As pointed out in this weekend’s Wall Street Journal, this is the burning question for those of us in the northern hemisphere as we enjoy our brightest days of the year. According to The Numbers columnist Jo Craven McGinty, the answers are:
- At least 2 milligrams per square centimeter—about one-fifth the depth of a piece of paper. Although this seems very thin, most people only put on about half that amount, so you’d best apply your sunscreen twice.
- Go for at least an SPF of 50. However, do not sweat it if all you have on hand is SPF 30, or the level 50 costs more than you care to pay—the difference is minor as you can see in the graph I made by fitting the FDA data WSJ
provided to a curve (using Design-Expert® software).
It seems to me it would be best to stay out of the sun as much as possible, and, when you do, cover up, but seek the advice of your physician or other qualified health provider, such as a dermatologist. Be careful out there!
PS. McGinty detailed a study that found a significant advantage to increasing SPF from 50 to 100. It being done via a randomized split on 199 snow skiers bodes well. However, the research was sponsored by a sunscreen maker. An independent, contrary view of 100 SPF pros and cons is laid out here.
Ear, ear: 7-year-olds hear 70% from right versus only 55% of speech to left
Jo Craven McGinty, the Wall Street Journal “Numbers” columnist, provided in the February 3rd issue the surprising ‘heads-up’ that children understand much less of when spoken to from the left than from the right. The difference in comprehension stems from a discrepancy in lengths to which speech must travel through the brain. This had been thought to become moot as nerves develop—the “right-ear-advantage” (REA) becoming clinically insignificant by adulthood. However, as reported by WSJ, new findings presented by Auburn University researchers in December to the Acoustical Society of America, indicate that even at ages 19 to 28, a challenging communication may be understood at a rate of 40% more when delivered to the right ear.
The Remarkable History of Right-Ear Advantage published in the January 2018 Hearing Review reveals that REA returns with a vengeance at age 60 and beyond. Perhaps a podcast will be produced to speak on this phenomenon. If so, I plan to put the sound bud into my right ear.
No reason to worry yourself to death over downturn in USA life expectancy
National Center for Health Statistics (NCHS) researchers announced this week that life expectancy for a baby born in 2016 fell 0.1 percent to 78.6 years. First off, this reduction is so miniscule that it cannot be significant. It definitely is of no importance per se. I do, however, concur with those who cite this statistic as a call for alarm by it being driven down by the epidemic of opioid deaths.
The trick to interpreting statistics on life expectancy is to keep in mind it has a mathematical value that changes as an individual gets older. For example, men like me at age 65 can expect to live to age 84, primarily because we made it through high-mortality childhood and the perils of being a young adult. Look up your expectancy at this Life Table from the Social Security Administration’s (SSA) Office of the Chief Actuary and give yourself a year or two extra by it being a bit dated (me being optimistic in the continuing advancement of medical care).
If you want to be more precise than the SSA tables, check out the calculators posted here. One to avoid is the “How Long Have You Got?” calculator, which comes with the caveat that “each time we’ve tested this calculator we are expected to pass away on the same day”. On the other hand, I think you will like the results from the Easy Surf life-expectancy calculator*.

Costa Rica — the happiest place on Earth
Posted by mark in Uncategorized, Wellness on November 6, 2017
Life-sustaining Costa Rican “broccoli” tree towering over rain-forest trail on the slopes of the Arenal Volcano.
The latest issue of National Geographic awaited me upon my return from a wonderful vacation in Costa Rica. Based on my pleasant encounters, it was no surprise to me that this Central American country came first on the feature article about “Happiest Places”. Costa Rica also ranked #1 on the Happy Planet Index (HPI). See the Today.Com video here for the heads-up on what distinguishes Costa Rica and other joyful places around the world.
It seems to me that the recipe for happiness varies quite a lot, but one aspect of Costa Ricans that I like is them living “pura vida”—the pure, or simple, life.
“What I argue for are statistically driven things you can do to optimize your environment so you’re more likely to be happy for the long term.”
