I do know my personal limits, though, and it has to do with eating bugs. Nuh uh, no way. I almost can't stomach watching the Klingons eat gagh/Ferengi eat tube grubs on TV, and that is just fiction. Which is why I say I have an iron stomach to a "decent" degree... there are some things I just won't do. I once watched Mike Rowe of Dirty Jobs go to Minnesota and catch leeches from a lake up there with a couple of professional leech-gatherers - these crazy brothers then took some of the leeches and grilled them and one guess as to who had to sample... almost lost my lunch on that one.
