I definitely think that Powell is a much healthier specimen than McCain.
If they were both locked in a room full of cats, i have no doubt in my mind that Powell could apprehend and asphyxiate the beasts at a rate approaching 10 cats a minute. On the other hand, i fear McCain would struggle to choke even a sickly three-legged kitten before collapsing on the floor breathing heavily.
