Sweating, and time of day

[flexagon]

Out of the 5 or so posts I'm dying to make, this is the shortest: does anyone else have a correlation between when they sweat and what time of day it is? For a while, at work, I was noticing I'd get armpit circles at around 4 PM and I was blaming it on my afternoon coffee. Then I went to decaf (or skipped entirely) and it still happened. This is, by the way, the thin button-down shirts that are under discussion... I'm generally not nearly so nasty as to sweat through knit cotton. Finally, last weekend I was wearing a tank top, so there was no fabric to bother the area at all. But as I was strolling around in the afternoon I suddenly noticed I had some sweat... and there it was, 3:50.

Am I the only one?
