Interesting ideas, although... I have a MAJOR problem with heights. My only real phobia. (I'm even okay with spiders crawling on me!) Although, I've always said if there was one of the "height" extreme activities I thought I could do, it would be skydiving. For some reason I think being up SO high in the air there would almost be no frame of reference to the ground, as opposed to, say, bungee jumping where the ground is pretty much RIGHT THERE. I have no problem, by extension, with commercial flying. Interestingly, my W's take on this is the opposite-- she thinks it would suck to have to think about hitting the ground all the way down if your chute failed, whereas with bungee jumping you'd hardly have time to worry about it and would so be more inclined to try the latter!
I am not all that crazy about working out, either, BUT... I do enjoy the results enough and get enough of a mental boost (I am a firm believer in endorphins) that I find it rewarding.
