It sounds like a joke based on a basic misunderstanding of science, but a man who’s been slowly injecting himself with snake venom may now provide a source for a universal antivenom.
Over nearly 18 years, the man, Tim Friede, 57, injected himself with more than 650 carefully calibrated, escalating doses of venom to build his immunity to 16 deadly snake species. He also allowed the snakes — mostly one at a time, but sometimes two, as in the video — to sink their sharp fangs into him about 200 times.
This bit of daredevilry (one name for it) may now help to solve a dire global health problem. More than 600 species of venomous snakes roam the earth, biting as many as 2.7 million people, killing about 120,000 people and maiming 400,000 others — numbers thought to be vast underestimates.
