A producer on the show Man vs. Wild has revealed on Twitter how a savage snake bite in California nearly cost him his life.
Steve Rankin says he was climbing over a tree when the fer-de-lance snake bit right through his boot and deep in to his foot.
The poison from the viper set to work immediately, as huge parts of Rankin's foot skeleton were exposed. He was helped by his team, hobbling for around two hours until he could be taken to hospital by chopper.
Around a week later, and following a delicate skin-graft operation using layers from his thigh, he has posted pictures of his recovery on the social networking site. He also noted how his team saved his life.
