I have gone cliff jumping (into water, obviously, otherwise I wouldn't be writing this), I've done the rip cord, I'll ride any roller coaster you put me on and love it, but the high dive? Not so much. It just is not a thrilling feeling for some reason. That drop in your stomach occurs on the roller coasters, while jumping off a cliff, but 20 feet into the water off a bouncing board is somehow different.
A few years ago I jumped off a diving platform (you know, those super high, mega high dives that Olympians use) with my friend Devin, and I am still getting over it. He was so excited, and I had to go because I dare myself to do these things. But I hated it. And I remember the water hit my butt so hard that it stung for quite a while (I bet you didn't care to know that little detail).
I make myself go off the high dive whenever I'm at a public pool, because I feel ridiculous otherwise. "Bailey, you're 24, that 6 year old is jumping off the high dive." But perhaps this asks the question that we should all reconsider, if all your friends jumped off the high dive would you?
