You are so "sweat"

Remember how, in junior high (and hopefully not older), someone would sign your yearbook and write sweat instead of sweet?
Just a thought as the topic of sweat came up today after spin class. My friend Sam and I--as well as one of our instructors--sweat pretty heavily during class. The instructor, whom I'll call James, can wring out his shirt when he's done and there are always noticeable puddles on either side of his bike. Our teacher today, who is not James, said she heard that if you sweat a) a lot or b) not at all, then you're in good shape--but if only moderately, not so much.
So here's an article to explain some of this. And another.
Hope you are having a SWEATY/SWEET Saturday.
