Growing Older and Bigger: isometrically or allometrically?

Are we growing isometrically or allometrically?

Meeting old classmates at reunions can be enormously interesting, especially if one hasn’t seen one’s former classmates for decades. In my case it was 50 years that I hadn’t seen the “little boys” who as 10 and 11-year olds had been my buddies. Alex, who used to be one of the smallest had grown into a really big and strong man; Lindeman, who was a good swimmer even at age 10 seemed to have grown less upward than sideways and Thomas, who used to have such wonderfully shiny black hair, now was snow white; some of the others had no hair at all. A few had retained their childish features and proportions and even after 50 years were recognizable, but the majority had changed in size and proportions. —>—>

Hibernation : Sleeping Beauties’ Secrets

How to sleep away the bad times

Wouldn’t it be nice to be able to just sleep away a bad phase of one’s life, to hibernate until things would get better, to be like a bear in its den in the midst of winter? But hold it, the bear is not a good example. Physiologically it does not truly hibernate; it only rests.

The Great Motivator Taste

Wasn’t it Columbus’ reason to discover America?

The sense of taste in humans, compared with that of other creatures, is poorly developed. For example, the threshold for tasting alcohol requires a 20,000 times greater concentration than that, which elicits a response in our olfactory receptors of the nose. Yet, we owe it to taste, not greed for gold or missionary zeal, that Columbus departed westward in search of a shorter route to the “Indies” and that Vasco da Gama a little earlier had successfully navigated around the tip of Southern Africa. European food in the Middle Ages must have been terribly bland and boring and to make it at least halfway palatable spices like nutmeg, cinnamon and cardamom, to name but three, were precious and needed from the Orient, from the “Indies”. —>—>
