Elite Fitness Unhealthy?

Okay, I'm not quite gone yet...

Art De Vany addresses (via a Mark Sisson essay) a question I ask myself frequently when I read his blog. Namely, is the pursuit of elite fitness for sport unhealthy, big picture-wise?

The essay mostly references endurance athletes, and I ask a question about that in the comments.

There, now I'm outta here. Looking forward to reading replies either here or there when I get back next week.
