 I used to have a fear of heights. I don't know where it stopped. But if I'm on a roof I'm not familiar with, especially a flat roof, a tall building that's taller, much taller than my house, and I would look or even watch a video of someone looking over the edge, it just makes my stomach just go upside down, man. It's crazy. Same with me. But for the most part, I don't have a problem with it. It's just one of those that looks like, oh, my gosh, this is extremely dangerous.
