High place phenomenon is that weird urge you get to jump off a bridge.
I don’t get that. I get a strange variation on that. I remember standing on a bridge one time holding a tennis ball. I wondered how hard it would be to get the tennis ball back if I dropped it. So I dropped it, entirely without meaning to. Sure enough, it was no easy job getting the tennis ball back.
In London I never liked standing at the front of the queue to get on a rush hour underground train. I always felt like I’d be pushed by the people behind me into the oncoming train and fall onto the tracks. Sometimes I wondered what it would be like to push someone in front of me. But don’t worry, I never tried it. And I stay right away from trains these days.
Because there’s always the tennis ball.
