Meet Steve Ludwin. He's 51 and for the past 30 years he's been injecting himself with snake venom.

He says it hurt - a lot - at the beginning but now his body is almost immune and he's donating his blood to science.

He is a living specimen in a new exhibition at the Natural History Museum called Venom: Killer and Cure.
