And another thing--re: the IM challenge--Andrew was some kind of hero for sure, and not to take anything away from him, but I think that Shawn lost it for the other tribe. If Andrew had dropped his weight at 160, Morgan still would have won b/c Christa had more weight than Ryan and he would have lasted longer. The critical loss was Shawn dropping his weight so early. If he'd been able to last until, say, 180, even briefly, it would have been much closer.
Christa is an amazingly strong woman, but how humiliating for Jon that she beared the weight instead of him. She may even be bigger than Jon, but men are genetically designed to have greater muscle mass than women. Even a very light man should be able to carry more weight than a strong woman. It's beyond me why they voted out Trish instead of Jon. He's obnoxious, can't steer a boat, and is weak.
