A story about the dedication of some scientists (simple and clear)

Bauer Hurst is an American scientist who studies snake venom. When he was a child, he saw that thousands of people in the world were killed by poisonous snakes every year, and he decided to develop an antivenom. He thinks that people with smallpox will have immunity, but can they also have immunity after being bitten by poisonous snakes? Can antitoxic substances produced in the body be used to resist snake venom? He imagined that it was also possible. So from the age of 15, he injected himself with a small amount of snake glands, and gradually increased the dose and toxicity.

This experiment is extremely dangerous and painful. Every time he is injected, he will be seriously ill. The snake venom of various snakes has different components and different modes of action. Every time a new kind of snake venom is injected, the original anti-venom substance will not be competent and will be tortured by the new anti-venom substance. He was injected with 28 kinds of snake venom. After a dangerous and painful experiment, I finally got something. Because of its own anti-toxicity, King cobra, Indian blue snake and Australian tiger snake have all bitten him, but every time they survived. Green snake is extremely toxic. Hester is the only living person who has been bitten by green snake in the world. He was bitten by a poisonous snake 130 times, and he was safe every time. Hester analyzed the anti-venom substances in his blood and tried some anti-venom drugs, which have treated many people bitten by poisonous snakes.
