"Survivor" host Jeff Probst visits "The Talk" Tuesday and spills details on season 40 "Winners At War." Probst reveals why former legendary winners Boston Rob Mariano and wife Amber (Brkich) Mariano, who originally met on the show, agreed to return. "His point was, we want our kids to see how we met. They were young when they did the show." Getting real about the contestants smell factor on the island, Marie Osmond asks, "How bad does it get?" "It's horrible," responds Probst. "That's the question, when? It's about like, 13, 14 [days], in the teens. When you get in the teens, suddenly I go to tell them what we are going to do, and there is this overwhelming, like a locker room [smell], with clothes that have been in a closed locker for too long. But they don't smell it. They all just smell like each other."
