I take issue with JP telling Osten that his tribe "adored him". I think they stuck with him hoping they could put his muscles to work. Just shows that the brain is the strongest organ. I hope he watches himself on TV and sees how his tribe mates are noticeably skinnier and then sees himself looking hale & hearty and feels at least a twinge of shame.
I think muscle guys really wimp out when put on crash diets. It was the big muscle guys who had the worst time in the Donner party. (You know, 49'ers trying to reach California, snowed in, etc.) It takes more calories to keep them going. Combine that with fear of any creepy crawly, open water, open sky = worst survivor ever. What a waste of time Osten turned out to be.
