Last night in the sauna, our European friends asked again for an explanation of the Fahrenheit scale. It boggles their mind that we here in the United States still using the clumsy Fahrenheit thermometer readings, instead the easy Celsius version.
Celsius determined the freezing point of water as zero degree, and the boiling point of water as 100 degree. Fahrenheit, on the other hand, placed his zero point at the lowest temperature he personally ever measured (in an artificial cold mixture of ice and salts). He then determined the moment when ice forms on non-moving water as 32 degree. And a third fixed point was when he put the thermometer under his arm – which he called 96 degree. Things could not be more messy and arbitrary than that, methinks.
Not to take away from Mister Fahrenheit’s merits: He invented the thermometer. But his temperature scale outlived its usefulness. It is only used now in the U.S. and in Belize (does that tell us something about the political situation of Belize??). The Fahrenheit scale should go where also inches and feet and the American pound should go: On the garbage heap of history. It is time that we introduce the metric system. Mainly so that our children in school don’t spend an inordinate amount of time learning to work with one sixteenth of an inch, and something like that. To handle inches and feet make you fit for construction work, but not much more. The metric system is easier, makes more sense – and can take students to science and computer language and into the difficult future … if they didn’t have to learn inches and feet and Fahrenheit and miles and uneven pounds. As a former math teacher, mathematical prowess is important to me – and I don’t like at all that we are taking only place # 27 globally in math skills.
Daniel Gabriel Fahrenheit (1686 to 1736) died already at age fifty. I wonder if he died of mercury intoxication, because he also invented the mercury thermometer. He actually started his career as a naturalist, after his parents died of a mushroom poisoning when he was in his teens. He was born in Gdansk, not far away from where I was born, and is a contemporary of Johann Sebastian Bach. – And, no, Anders Celsius from Sweden did not die of mercury intoxication; he died so young of tuberculosis.
Meanwhile, and interrupting my writing, I took a bath in the ocean. The water is rejuvenating, stimulating and cooling. In former years I had to leave after five minutes because I was cold to the bones. For the last few years, we leave because it gets boring. Anybody here still refuting global warming? Here, in down-east coastal Maine, we feel the consequences. Also by increased rains: We had water in the basement - the cement is broken, water comes in from all sides. Which had a good side-effect: We finally had to clean up the basement; it was overdue for about twenty years ...
Of course, it is still gorgeous summertime in Maine. We sleep and eat, we read and discuss, we do sauna (and a dip in the ocean afterward), and go for hikes. The other day, we had a lobster bake, directly at the ocean with churning white water, on wooden benches. Life could not be better. That is what the Natives must have thought hundred of years ago: This was their summering area, and their spirit of reverence for this place is still in the air. They would come from afar and meet here, to indulge in clams and mussels, lobsters and scallops. Then for two hundred years this paradisal spot of the Earth, was used cutting down the old growth, then farming it, which turned out not too successful – this is mostly barren clay and rocks around here. Afterwards, sheep farming, and then, nearly a century of neglect again so that trees could cover the land. Not like old growths 0 no, that we will never get back again. But still beautiful. Now, a few summer cabins are tucked into the woods, barely visible during day time because Maine has an ordnance in place that constructions need to be away 100 feet (30,48m) the upper shore line. But at night you see lights shimmer and sparkle through the forests – more than one would guess during the day.
I have read the German mystery, and found it satisfyingly light fare. Now I am reading Hans Fallada’s Alone in Berlin – and that is not light fare. But a marvelous book. That there was one German who could write about what happened to the population during Nazi time – I feel it is kind of a redemption.
My musings from Maine can’t end without describing a few of the tiny medical emergencies we had so far – and hopefully, we will not experience worse: Cat allergy: Andrographis paniculata; leave out all dairy to reduce inflammation and mucus production. A cut foot from a stone: Saltwater; tea tree oil. A sty (hordeolum): lukewarm teabag on eye; Echinacea, goldenseal and GSE (grapefruit seed extract) from the inside. An underarm rash (likely fungal): tea tree oil. – Everybody is doing remarkably fine. Read More

Have You Coddled Your Hippocampus Lately?
February 2, 2011
A recent study shows that brisk walks boost memory in older adults. And makes your hippocampus swell visibly on MRI. I bet this also applies to younger people.
The hippocampus is a worm-like structure deeply buried in your brain that is involved in memory formation. In Alzheimer, it is the part of your brain that will show the first signs of degeneration. A youthful hippocampus gives you mental plasticity, the opposite of which would be the obnoxious inflexibility that some older people show. About six to nine miles a week in this study was linked to better brain function. Walking even more did not seem to have more effect on the brain.
It comes down to walking ten minutes in one direction, turning around and walking back ten minutes, which can be done during lunch hour.
Another study showed that people who walk faster live longer. That bodes badly for me – I am a slow poke. But we can safely deduct that people who don’t walk will not make it long at all.
Walking also boost mood. If I would be a moody person (which I am not), I would do three things: go for a daily walk during daylight, end every hot shower with a cold one, and take herbal preparations – in women particularly, herbs against PMS or helping with post-menopause. Not to mention that I would turn to fresh, nourishing food and away from junk.
Walking per se is good for you. Two other studies have shown, that the effect is even better if you walk on uneven surface – like on pebbles, at a beach or in hilly terrain. Walking on pebbles decreases high blood pressure, and makes you less likely to get Parkinson’s. Using more muscles and consequently more brain can explain these results.
The most dramatic effect, I think, that daily walking can have – besides on memory, longevity, hypertension, Parkinson’s and mood – is that light boost vitamin D production under your skin – even if it is just the pale little area of your face reaping the rays. Vitamin D has become an important research focus as it wards off bone loss, cancer, multiple sclerosis and infections.
Walking will also lead to less weight and fight the dreaded metabolic syndrome (diabetes, high blood fats and hypertension) better sleep – all exercise does. And better sleep has been shown to increase overall performance, mood and resistance to infections.
In New England presently, walking the icy streets among huge snow banks is not that enticing. But I bet snow shoveling has all the above benefits, too – if you avoid hurting your back and don’t slip on the ice. At least I hope. Because I spend the morning digging out our walkway and garage driveway. At least this I know: The cold stimulus is a trigger for better immune function: Snow-shoveling in freezing temperatures improves my ability to better fend off flu and the common cold. Read More
Don’t Know About the Biochemistry of Birds
December 11, 2010
Today the pond was frozen over for the first time this year. The Canada geese have flown away to a place with still open waters, and the lone cormorant that, for weeks, had greeted us every time from the same spot is gone, too. We still can make out where he always had been sitting – a white sheet of guano at the edge of the reservoir (presumably soon being washed into the reservoir, enhancing our drinking water…).
We marveled at the bird every time we walked by. Why was he always sitting on that very spot so steadfast? Hatching time was long over. He was not deterred by the many passers-by. We had gotten fond of him, and his whimsical determination.
My husband and I take our walks to catch up on each other's lives; we are talking to each other (helps a marriage to survive). And to catch a ray of sunshine – so precious at this time of year when the sun gets lower daily. We want to build up some vitamin D under our skin to get through the winter without colds or cancer. I don’t know about the biochemistry of birds, but the cormorant must have thought along the same lines: Get in as much of the goodness of the sun. as long as it lasts!
Of course, a walk in the dark exercises your body, too. But walking (or running or playing ball or finishing up fall cleaning in the garden) in light has the extra benefit of helping your body to produce vitamin D under the skin. Lighter skin produces it more easily; dark skin needs longer exposure. Besides helping fight infections and cancer, vitamin D is essential for bone strength – and doing something outdoors, moving around, gives an extra boost to your health.
If we live right, we are able to do away with artificial vitamins. Isn’t it marvelous that the body finds the required vitamins in its food and produces some under the skin? Of course, the food has to be fresh, not processed – because artificial things (let’s not even call them food!) are devoid of what really nourishes your body. It has to be this way – that you find all your requirements in fresh foods – because, otherwise, how would have mankind ever survived without the multivitamin from the drugstore?
We do eat cod liver about once a month – giving us a hefty dose of vitamin D (along with vitamin A). It is delicious. But probably polluted – so we don’t have it often. If you don’t like the idea of eating cod liver, get a good cod liver oil preparation and take it during the winter months.
Our walks keep us healthy. Winter is not a time to stay indoors; it is the time to bundle up warmly, march out and come back an hour or so later with red cheeks, ready to sit in front of the warm wood stove again. That walk in the cold gives your body a stimulus to balance itself according to the season – similar as a cold shower does: Cold is a healing stress – if not overdone.
Out there, with the cormorant or the Canada geese or just the still surface of the frozen pond, we bond again with Nature and rediscover that we are part of it, and rediscover our spiritual home. Read More
