• If I'm high up I often can't look upwards without getting symptoms of vertigo. Ditto standing at the base of something very high e.g. a powerstation chimney.

    I once had the chance to go up on the gantry above a velodrome track. I got so far, then looked up the gantry ladder and suddenly things got spinning and it felt like I had been tazered on my perineum. I couldn't move any further forward, thankfully I could still climb back down and as soon as feet hit ground I was fine again.
