Well....
the one advantage of fat is that it floats and is also stored energy, so the fatter one is, the better chance you got if you go overboard. Of course, there also needs to be a tough, never quit mindset, which isn't that common.I remember when I was in the army and going through a selection process to come up with the best of the best in my unit to train with the Dutch in Aruba. One of the requirements was to be able to tread water in full combat gear for 10 minutes. I was in great shape and that sounded easy. I blew everybody away in all the other tests, but that floating test killed my chances. I think I lasted about 2 minutes. I didn't have hardly any fat on me, but the guys who did had no problem at all. They could just put their head back and relax. I tried that and sunk like a rock twice.
