Though I`m not afraid of heights, I usually avoid standing on the edge of something tall because I get this unexplainable urge to just...jump. A little voice in my head goes "whoaa..this is high...jump.jump.jump.jump" and I actively try to silence it. I would never act on behalf of my little voice, but I don`t understand why it`s there in the first place. I never had problems with depression, I wouldn`t commit suicide and, all in all, I really like life. I like tall buidlings, mountains, basically anything that lifts me up from the ground. I could spend nights watching the city from the top of a building. So what`s with this urge?
