Sure. Why not?
Because I have vertigo. I can't get on the roof without my head spinning. If I'm on the 8th floor of a building, go over to the window and look straight out, fine...I just can't look down.
Anyone should know you can't hand hold a 6x7 camera at speeds below 125 unless you have nerves of steel. I shot a lot of night scenes with that camera at anywhere from 2-10 sec but it was on a ten pound tripod, mirror up after focus.
