I think singing hymns has to be the most corrosively boring activity imaginable. They were all written by pious white men a couple of hundred years ago (at least I assume they were white, since they were scoring these hymns in the British Isles, Scandinavia and Germany). Prayer is not so bad because it sends positive messages t the subconscious and when done publicly is a communally bonding experience. Even atheists can get those two benefits. I'm an agnostic who believes in some spiritual essence in the universe wthout having any idea what it is More to the point, the grinding boredom of Church services militates in favour of misbehaviour; particularly if one is already a budding sex addict and has an almost constant boner in Church from imagining how various parishioners look under their clothes or, well, just on general principle/principal.
