In the exerciser, it was about 95% slow-twitch. And so it's extremely clear-- again, I don't know if maybe their set point was a little bit higher towards that, and the non-exerciser devolved down to his place or the other one, but it doesn't matter. I mean, you're going from 40% slow-twitch in one case to 95% slow-twitch in another case.
