I can't say I will never try my few least favorite foods again. Occasionally I give things a third or more try. Also, if I am served a disliked food as a guest, I try to eat at least a little. I won't downright refuse it, unless it's presented as a choice vs. a sole main course. As for never wish to try, I doubt there would be many. I suppose I would unequivocally refuse eating certain bugs, especially alive, or anything still living. OR something like monkey or dolphin, or an endangered species. Also, no cannibalism or total inedibles (i.e. a car or plastic bottle). And I sure as heck wouldn't eat my pet, even if starving to death, yet maybe another person's pet? I really am among the best of sports when it comes to eating.

What is an activity or sport you would never do, even if a huge payment would be offered for doing so?
