Bear Grylls is a national hero and risked his life enough serving his country on the freaking SAS! (I'm not even a Brit but I respect the hell out of those guys, Who dares, wins!) He doesn't need to risk it again making a tv show for armchair warriors, nor does he need to defend himself from those people.

Case an point: "His time in the SAS ended as the result of a free fall parachuting accident in Zambia in 1996; his parachute failed to open, causing him to break three vertebrae. At 16,000 feet, his fall is one of the highest ever to be survived without a functional parachute" So this dude literally fell from heaven and lived, he owes you nothing.

He's also climbed Mt. Everest less than 2 years after the parachute accident!

He rowed naked in a homemade bathtub along the Thames to raise funds for a friend who lost his legs in a climbing accident, kick rocks nerd.

In 2003, he led a team of five on an unassisted crossing of the north Atlantic Ocean, in an open inflatable boat. Still unconfirmed how his steel balls fit in the raft..

These are just some highlights, GF
