Yeah, you're right Thoul about some of them not being in the best of physical shape. But then, that is supposedly the premise of the show - get the ordinary looking, every day kind of guy or girl "star". I think I read somewhere that they all have to do a physical before they join to make sure they are physically able to do the show, but that doesn't account for injuries that may happen such as leg or back ailments, etc. There certainly seems to be more and more of those kinds of injuries with each season that passes also.
And, in last night's elimination round, the co-host of the show, Samantha Harris, couldn't even hardly talk because she had laryngetis (sp?) and the doc had told her to "rest her voice". There is always something happening on this show, lol.
Also in last night's "double" elimination round, 2 stars were sent home. Holly Madison and Steve "the apple computer guy" were eliminated. No big surprise there.
