I was travelling down from the 10th floor of my office building in the lift when I bent over to fasten my shoelace. I was suddenly dizzy and disoriented and had to kneel down to stop myself falling over. I never have any difficulties travelling in lifts, but presumably this was in some way caused by the fact that I was descending. I tried it again a week later with much the same effect. Why does bending over in a descending lift make me dizzy?
