There is nothing speedy about me, and never has been. My sports have always been endurance ones.

I do know that if I don't eat my ususal huge protein-laden breakfast I run out of steam during the day. (I eat dinner for breakfast: pork chops and mashed potatoes and broccoli, stuff like that)

So I guess I'm looking at protein from a fuel standpoint rather than a recovery/rebuilding standpoint, but I know I certainly need the stuff.
