I remember getting stuck on the motorway once in a traffic jam. That leg of the journey is always unpleasant since I have to go about an hour with no services. This time there were roadworks and delays. Eventually I had to get out of the car and pee at the side of the road.
It's not a great prospect to have to pee on the motorway at the best of times but to be stood there for what seemed like two or three minutes while cars crawled past at two to three mph was the pits.
I felt quite pleased when I got back into the car, thinking that my prostate must be in decent condition for me to have been able to hold that much liquid.
