LOL i can last around 25 miles...but I make sure I drink some cranberry juice at the end of it, you know, to flush things out. But yes, doesn't it provide anxiety? It's like sitting in a crowded movie theater, and 45 minutes in the movie the urge to go hits you like a ton of bricks. So you either sit there in misery so as not to disturb anyone around you, or get up and have everyong huff and sigh.
