Human biochemistry works at its best at around 98 degrees F, and while adaptation to living in and visiting different environments is possible, from the Mojave to the moon, adaptation to altered body core temperatures is not possible.

A great anatomist used to close his opening lecture to beginning medical students with words that apply equally to our own undertaking.
