"Roll on your right and lift your left cheek." I say this dozens of times every day. Probably 1/3 of my ladies roll on their left. It's understandable though. Even if you don't have directional confusion, I am convinced that all the blood goes between the legs and away from the brain for a few minutes. One lady that rolled onto her right and lifted her cheek said "this just ain't right." Yea, I admit that it's pretty messed up.
