Unless I'm in a hurry, or headed out the door in outdoor clothes, I always sit, no matter what I am doing.
This allows a minutes contemplation of the infinate, and pursual of whatever books or magazines I have 'on the go' in the loo.
One thing I have noticed is girls pee like mares (three secinds, all done), guys trickle longer... due to a longer urethra perhaps? I thought it was only me, but in a discussion of 'wierd stuff about girls' that I had with some male friends (yeah girls, we talk about you as well; the sport is a cover, the minute you're out the room we talk about your skanky underwear and cellulite), it came out that this was a common thing.
People living in glass paradigms shouldn't throw stones...
