Bathroom Breaks

I don't know what it is about traveling, but taking bathroom breaks need to be made into a science. As I am spending about 2 solid days on a bus going down to Florida, I have had time to reflect on this issue. First, you start drinking water. Then, you stop to get coffee. Then, you are back on the road again and are in dire need of using some facilities. I'm not sure what it is, but once you realize you have to go to the bathroom, there is some kind of chemical imbalance that happens in the brain which makes you think you are actually more thirsty with a full bladder. I am going to blame this on an overactive hypothalamus. There has to be some correlation between buses and the hypothalamus.
