Well, I don't know if this always applies, since now I seem to be at the point where I am a little creaky in the AM and I need more recovery time from all sports...
But, I laughed when someone said that we are so uninhibited about discussing this. Once I was with some cycling friends, along with some "regular" friends. The non-cycling people were shocked at the level we were discussing our bodily functions, along with other assorted personal things, like peeing in the woods.
I even talk about this stuff with my exchange student son, who is a cyclist, but only 23 years old... I have intimate knowledge of his entire digestive system!
