This is Bill Haaste:
He injected himself with the venom of several types of snakes to gain immunity.
20 of these near-fatal incidents were fatal, and many of them left scars on his hands.
More than 3 million snakes have passed through his hands since 1917, when he was 7 years old and picked up his first garden snake. His desire to explore species led him to drop out of school and start an entertainment company that put on snake shows.
In 1947, Haast opened the Miami Serpentarium, where he performed snake shows, draining their venom, and conducted various research projects.
Based on this research, Haast helped more than 6,000 people cure snake bites with his venom extracts to make antivenom. Even without formal training, the American had excellent knowledge of the science of snakes and venom extraction.
The self-proclaimed Snake Man thus possessed antibodies to several different species of vipers, and on 21 different occasions, he was able to save the lives of people bitten by the reptiles by giving them a blood transfusion.
With this, he realized that certain poisons could even prevent diseases such as multiple sclerosis and arthritis. He believed that these poisons, which he injected into himself daily, were responsible for him reaching the age of 100 in golden health.
