Well, for some reason, this was not an unusual topic of conversation in my house, growing up, nor now. My husband and I like to joke that cycling is the automatic "cleansing activity." No matter how short of a ride I am going on, I always "go" before a ride. Sometimes more than once. It doesn't matter the time of day, or if I have gone earlier. Most of it is nervous energy for me, but when my husband mentioned the same thing happened to him, I wonder if it is our body's way of getting rid of stuff before we are out in the middle of nowhere.
Jolt, I agree. Most Americans are full of cr@p. I am pretty sure the only reason I had issues with this as a kid and teen was because I ate hardly any fruits or veggies. In fact, when I was 5, I had to be put on a special diet and take some awful chocolate looking medicine (I remember my mom shoving it down my throat from a spoon) because I was living on bread and butter and milk, which wreaked havoc with my digestive system, to say the least.
