A guy in Switzerland recently set a world record by jumping off the top of a 193-foot waterfall. This would totally freak me out because they had to aerate the water he landed in so the impact wouldn't kill him. But the crazy part is it still could have because he hit at over 75 miles an hour. I have what I call a healthy fear of heights so I'm pretty sure I couldn't have even stood on the cliff let alone jumped off of it.
