Injecting Venom

Why would someone inject themselves with venom? Thousands die because of venom! But one man didn't die. After a snake bite several years ago he choose to not go to the hospital. His name is Steve Ludwin. He has been injecting himself with snake venom for many years and didn't die but is actually healthy. At first his body's reaction is horrific with many colors showing up on his skin and sometimes has to go to the hospital. After doing many injections over time his body is ust to the injection and doesn't react as badly when he first started. When he do studies about his body he found out his body has an aging process of a someone who is in their 20's. I think it's fascinating but i wouldn't do it.
