I so miss it.
There isn't anything quite like it...
Endorphins ... nature's wonder drug.
I abused my knees. I'd always blamed the skiing. The revisionist corrected my misconception. He said that the bone doesn't support that. He said he'd bet me that he could guess the kind of runner I was.
Then he looked at me and simply said:
"a dumb one...you ran on asphalt and you didn't walk down hills..."
He was spot on. I pounded my knees to dust running down hills as hard as I ran up them.
I sure as hell don't miss smoking though.
