Well, isn't it a scientific fact that nylons and make-up add at least 15 degrees to the heat index?

It's true that certain inalterable things happen during childhood development. I hadn't heard that about the sweat glands forming only in the first month of life - in which case you would really have to consider what month a baby is born. January in Boston is quite different from July...

However, acclimatization is another important process. It can take a few weeks for minor acclimatization, and a few years for long term changes. And adapting to certain extremes may always be impossible for certain people, whether due to genetics or the your childhood development environment. After spending two weeks with altitude sickness in the Andes while watching the natives casually jog up a slope at 18K feet elevation, I know I'll never have the aerobic capacity to deal with that.
