This man survived 200 snake bites, from cobras to mambas, and now his blood is helping scientists beat venom; know how

Tim Friede, a former truck mechanic, intentionally subjected himself to numerous snakebites over two decades, aiming to develop immunity. His unusual experiment led to a breakthrough in antivenom research. Scientists discovered broadly neutralizing antibodies in Friede's blood, paving the way for a universal antivenom that could protect against various venomous snakes and save thousands of lives annually.
