Just from the footage of Trump's near assassination. Just made me think, if need a body guard, whose job it is to take a bullet for me, I want that bodyguard to be really, really big, so that his body is way bigger than mine, so it covers mine. Also seen other footage of bodyguards protecting people in a mob, and they only got their charge out because they were just so physically massive, they could force their way through.
Its a job where physical size and bulk matter. I'd just want a man, an unusually big and strong man, to do it.
