What is more painfull?

[Galt]

I don't got a week between shits, but I am definately not regular. Normally I go every few days, but then sometimes I'll get doubled over with stomach pains and have the assplosions for a couple days.

Taking a piss is much more enjoyable than taking a shit. So with that logic, the reward of holding a piss would be much better than the reward of shitting.

So I'm going to go with holding a shit is more painful/annoying
