See Boy Run

It's amazing what a difference running in low-80's makes over running in mid-90's. My internal cooling system only barely has to kick in. And the shadows don't start chasing me like they do after running in that heat for half an hour.

Reminds me of an interview with some Olympic swimmer who said that he'd spend hours talking to the lines at the bottom of the pool while swimming (I mostly just sing to them in my head, but, anyway...); it only began to concern him when the lines started talking back.
