I didn't remember her metabolism, and you're right, that was an Eric-sim. And, to be honest. some of the more extreme consequences of her adaptation are probably stated a bit more strongly than I'd have done it on my own. The comment about her bone density being so great that she can't float, for example.
I remember talking to someone who had the job in the navy of ensuring/training people to swim. He found a lot of the better conditioned black guys couldn't passively float. They had too much muscle and too little body fat that they had to do something active to keep on the surface. Plus the majority of them had never learned to swim until the joined the navy. So it's not unreasonable.
