You will never and if you think,

then probably you will get horrified !!

But a man named Tim Friede   he is a scientist by proffesion has turned his proffesion into a endless passion of bitting himself to the snake bite !!!! Really you all will think i am not serious then if you dknt believe  i will post that youtube vidio link in the comment so that you can go and xheck him ..

This man at one point seems to be crazy because if you are bitted by a cobra you can be saved but within a limited time and if you have a proper access of anti venom and medical facility you wont lost your life , but what if you are bitted by a black mamba , 

Only 30% peoples can be alive, even if you get the advance treatment with an expert venomologist or a great doctor .. and even then chances of your life is very less 

Tim has bitted himself with over 200 snakes but he is still alive but the most shocking fact is that he does not consume or inject any anti-venom or a special  medication after bitted by a snake he just let the snake to byte him and he waits for 20 to 30 minutes and then relaxed and do his normal works of daily routein .

The biggest record he holds for letting to byte a PNG TAIPAN & BLACK MAMBA TOGETHER ON BOTH ARM  

His wife has divorced him by all his acts
