        There has been a chains of conversation and documentaries going on about snake venom injecting, there some people out there that have deadly snake at home they  milk snake's venom and inject it into their body with the hope to build immunity to it. They also believe that it may give them immunity to other diseases, if you have paid attention to  some television station documentaries about snake venom immunity then you are probably familiar with what you are about to read. On animal planet television station, they had a documentary on a guy name Steve in Miami Florida. Steve has been injecting him self with snake venom for a long time now, he usually inject the venom without diluting it, until one day that the venom almost killed him, he was rushed to the hospital, later after he had woke up from coma in intensive care unit, you will think Steve will learn from his mistake as a normal person would and stop injecting snake venom, but no; he did not stop injecting the venom. After he discharged himself from the hospital Steve continued his experiment on his body, the only minor difference form what he was doing before was that he now only inject venom diluted with distill water. Steve said he though he was the only one who does the experiment with snake venom with the hope to build immunity but he later found out that there was other people that do the same thing, more identified individuals surfaced and they too told their story about snake venom immunity, it seem like Steve and those other guys have something in common, it became clear that majority of this guys that  that practise self immunizing with snake venom are those people that handle snake on a daily bases, may be because the are liable to snake bites so they have to be ready for any bite the immunity is like their life insurance.
