of Troy: My mom and dad used to live in Florida and took house guests to the races for a diversion.

My dad always instructed me, "Bet on the horse that has broken out in the biggest sweat. It will usually win." Well, I would bet as instructed, but rarely did my horse win.

Back to those 250,000 sweat glands in the foot: You wouldn't think there would be any room for muscle, tendon and bone with so many glands taking up space.

I like the quote from Leonardo da Vinci on the link I posted above:

(the foot): "a masterpiece of engineering and a work of art"...
