Would you rather hold your poop or pee in for a long time?

I would much rather hold my pee, but if I had the choice I would hold neither.

When I was at school, I always used to hold my poop because I didn't want anyone knowing who was pooping. I did try not to go to the toilet at all, because I was scared the fire alarm would go off as soon as I started peeing or pooping.
So for me, I would hold poop.
