24's comments also came to my mind first, and I can bear out what he/she has posted. I don't imagine that the "G" resistance differences mentioned are really applicable to general aviation, or basic aerobatic flight. I belive that any healthy pilot still had G capacity beyond that of most GA aircraft!
It's also nice to be fit enough to be able to climb up to check fuel, and push the aircraft around on the ramp without getting winded!
