Good point Daisy.

My wife gets cold hands and feet when she is hiking, and has to wear warm clothes on the trail when the temp drops below 60. She will wear an undershirt, shirt, fleece, and jacket hiking uphill in 50 degree weather.

I get warm just walking on a level trail, and usually hike with little more than a single shirt and pants, even when the temps are quite cold.

But when we stop, she stays warm, and I immediately start getting cold--cold enough to get hypothermia if I don't do something about it. I have to put on every layer in a hurry.

Clearly body temperatures are just another area where your mileage may vary!
