Am I the only one who isn't a Dean Karnazes fan?

I really don't know too much about him... but his whole attitude of "if it doesn't hurt, you're doing it wrong (or not enough)" offends me. Seems to me we should be trying to avoid injury, and using pain the way nature intended, as an indicator of potential problems. Maybe it's just that he triggers my upbringing... but there ought to be more positive role models out there IMO.
