Sorry for the generic title, but I didn't know how to paraphrase this. Have you ever noticed that when you really have to pee bad, you can hold it in for hours with no real problems, but once you get within 10 feet of a bathroom the intensity gets 1000 times worse? Example, I drive an hour both ways for my commute. Plenty of times I have to pee real bad when I'm on the road. I find I can hold it in the whole ride home, yet once I walk into my apartment, the pressure seems to triple. Is this because my brains knows that when I'm in the car there is no where to go so it waits, but when I get home, it knows that I'll be peeing soon and it prepares to release? making the pressure even worse. Sorry for the vivid topic, but this always gets me thinking.
