So, I've met most of the competitors on that show. Of all the ones I met, Roland (rock house ox slayer) was the biggest prick but one of the most competent survivalists the show's ever seen. That guy could have survived another 100 days. He really tamed the land.
The women are badass. It's crazy that most of the shows runner ups have been women but none have won yet. It really does come down to BMI and weight loss. If I recall, Callie (runner up last season) was actually doing fine on food but she had still lost too much weight, so they pulled her.
Really wouldn't mind competing on that show in a couple of years, but my crazy metabolism would be my biggest enemy. I have to consume significantly more calories every day to maintain because my body burns it off so fast.
