There's a difference between restraint out of common sense and religious restraint. For instance, the Religion of the Chocolate Icecream Bucket forbids the eating of a whole bucket in a day. But non-RotCIB followers could very easily have the same restraint because they know it will give them belly-aches, provided they're not whale-sized individuals. So I'm not after those restraints, since I am curious about those which I as a non-religious hell-going person am not familiar with. Not much fun to be curious about familiar things now is it? So my question to the minority of god-fearing people is, what sort of restrictions does your religion put on you? What do you see godless heathens engage in that makes you think: I'd like that as well, but I cannot yield to the devil of temptation.
