Ofcourse! They have no camera crew (except at the med-checks and the tap outs).
They just have bits and pieces from every contestant that they have to stitch together to make a show out of it.
I thunk they do a pretty good job (not always...bu8t for the most part they do).
I can't get that guy out of my mind. The one with the autistic son. He about lost his mind. He ate mice. Ate snow. He held out as long as he could.
The part I can't get out of my mind is him staring into the camera with that blank stare, happy birthday to you
