Which do you consider yourself to be?
Had the idea for this thread by reading the "Sweating, how to prevent it" thread in the Diaper Talk forum. Hot natured people tend to start sweating at a lower ambient temperature than cold natured. I remember a friend of mine years ago who would be sweating when it was only 60F degrees outside, and with no coat on. Working inside a hot power plant in the Summer, I could really see a difference between a hot natured person (coworker) and cold natured (myself). We'd be in a 120F degree environment marking up drawings. In no time at all after entering the plant the sweat was pouring off of him. So much so, he couldn't hold drawings in front of himself to mark up, due to sweat drops causing the ink to bleed out. On the other hand, even after 20 minutes or more working with him I'd bearly start to feel sticky.
Now when it comes to cold, a hot natured person will feel more comfortable at a cooler temperature than a cold natured. The friend I mentioned at the outset was starting to sweat at 60F degrees with no coat. I was standing beside him with coat buttoned all the way up to feel comfortably warm.
Guess it's the same way with plastic backed diaper wearers, some will sweat more, some less, depending on their nature.
P.S. - Funny thing about me, I'm cold natured but love to get out in the cold in Winter. Suitably bundled up, of course.
