Famous Steven Lesk M.D. Quotes

“Our bodies, for instance have a need to move and were designed to do so. You don't take a tank, for example, that is designed for war, and use it to run errands downtown or to approach the takeout window at McDonald's. A sedentary lifestyle is anathema to what humans evolved to be.”

“We need to sweat more. Humans moved around in warm climates generally, which led us to lose our fur, and although there was some migration northward, activity in warm air makes one sweat. (Incidentally, the farther one goes from the equator, the greater the suicide rate. We evolved near the equator. There may be a connection there.) Sweating may have been a much greater excretion paradigm than we're now used to. Go toa sauna or a steam room. There are studies that show that using them reduces sudden death and cardiac mortality. Sorne toxins are stored in the fatty tissue of the skin only to be eliminated as we sweat. Along with sweating we need to replace fluids with good old water. Drink from the stream. Dietarily, ancient humans no doubt ate occasional meats but usually foraged around for edible plants and fruits. Not on a time schedule like a modern office dude, cave guy ate anytime he found something edible.”

“Sitting eight hours a day may take more of a toll than we realize. We were not designed for that. On the other hand, evolution helps us adapt to these modern demands. Those whose bodies are more tolerant of sitting have no doubt already been favored by natural selection.”

“Humans went from experiential and physical beings to conceptual ones, and one could surmise that in the future we will become even more brainy still. The changes in sedentary lifestyle alone are staggering. Dietary changes might have led to a diabetes since there may be different levels of pancreatic reserve. The explosion of carbohydrate intake that moderns indulge in may surpass the limit of the pancreas to endure, resulting in either childhood diabetes or later onset type 2 diabetes. We must be careful not to outsmart ourselves and in vanquishing the predators that plagues us for millions of years to create new ones. Having moved from chaos to order, we need to appreciate order’s value, to protect and enhance it. Any slide into chaos may well be swift and irreversible.”
