What makes people think that he gave up? I didn't see giving up, he finished the program all the way thorugh. Yes, he looked tired at the end, but that does not equal giving up.
And he is naturally pale like that. I have the same skin colour too. He's not intentionally making himself look green.
Ilooked like he just let the program go at the end. From the mid-point on, he became less and less focussed. It was easy to see that live. I'm not sure how it translated on the tv broadcast. I was quite disappointed, because he started out so well and all he had to do was not let it go and the gold was his.
