Lol. I'm inclined to agree with you there. However, considering that I'm writing this while I lay in bed with my foot propped up, having shattered a few bones during my last "weekend of extreme fun", I'm beginning to reevaluate my priorities. ;)
Ouch! I suppose my intuitions are influenced a little by the fact that I have never broken a bone or had any sort of serious injury. I suspect my priorities may be changing too in your shoes. (Well, possibly shoe, probably not the plural. Too soon? :P)
Most of the usual thought experiments that justify expected utilitarialism trade off fun for fun, or suffering for suffering. Here's a situation which mixes the two. You are offered to press a button that will select a random person (not you) and torture them for a month. In return the machine will make N people who are not suffering right now have X fun each. The fun will be of the positive variety, not saving any creatures from pain.
1) How large would X and N have to be for you to accept the offer?
2) If you say X or N must be very large, does this prove that you measure torture and fun using in effect different scales, and therefore are a deontologist rather than a utilitarian?
