As I write, I feel like I am in bladder insensitive mode. I don't need to go so it feels like I'm trying conjure up some distant memory. Perhaps bladder stress is like child birth where we have evolved, in the case of childbirth, to forget the true horrors of the pain so we can do it more than once, and in the case of bladder control, so that we recover enough not to start wearing adult diapers prematurely.
Bladder inconsistency makes it very hard to manage ones day, and more importantly road trips or outdoor concerts or festivals. For example, last Friday I'd drunk nothing all day, had a glass of Coke with my late lunch and then found myself on the verge of flooding the car 45 minutes later. We were on the freeway making a long drive home in traffic at 5pm. We had to pull off and take the street. While we were in a sketchy neighbourhood, mentally, being on the street assisted greatly in mind over bladder. On the street, you see options. A gas station, a restaurant, a bush, a gutter. They are possibilities and I daresay it is hope that has sustained civilised culture thus far and hope is no exception in matters of the urinary pouch. Even without actually stopping at any of these places, the option to do so eases the mind and the excruciating pain. On the freeway, it's a whole other pond. You are barely moving, but moving enough that you can't get out of the car. The only hope ahead is the sign marking 3/4 mile until the next exit, and if you choose not to demand that exit, you are now fixated on the next fraction of a mile until you can get off. This process may be as damaging to one psychologically as it may be kidneycally.
