That's because as an instructor, you have to assume that you're dealing with idiots. I don't know if "instinct" is the right word or not, but you can develop muscle memory in times of quick reaction. My muscle memory is that if I'm blasting a DH and I need to hit my brakes...my body automatically throws itself backward enough to counter the OTB effect.

Get this dill-holery out of my thread, kids.
