Don,
I suppose you can train the mind and body to do anything that doesn't come naturally, but instinctive control in this case, means that the mind expects everything to go in the same direction, and so does it automatically without having to think about it.
It just goes to prove that we haven't got as much control as we think we have.
At least, trying it out kept you entertained for a few minutes, and maybe a little smile as well.
