I don't get this whole temperature thing

It's cold outside, right? I'm new to this whole environment thing. I've spent less time in the real world so far than I had in the womb. So why is it that only my face is cold when I go out for walks?

I don't get it. The rest of my body is toasty. When az anyam takes off the pouch, the extra blanket wrapped around my legs, my jacket, my two hats, my gloves, my sweater, my extra layer of pants and my shoes, I've sweat through my regular clothes. I just don't get it.
