Body temperature is lower in older adults, is this beneficial or detrimental?
The idea of attrition started with Aristotle (384-322 BC) and was later adopted by the Romans, Muslim and Western European medical establishments. It became the basis for our early understanding of how the human body works. Essentially, Aristotle held that the human body was filled with four humors: black bile, yellow bile, phlegm, and blood. Any imbalance in these four humors resulted in diseases and disabilities. Aging is caused by the drying out and cooling of these humors. This idea had a wide following, and involved numerous hot baths and saunas in order to maintian our wetness and innate heat.
