theres rumors of him doing that "autoerotic asphyxiation"...when you jack off and hang yourself to get the ultimate high... he tweeted it about it in the past.... it went wrong obvioulsy.. they say Robin Williams did the same thing and the lead singer from Sound Garden, Chris Cornell as well... if i were to kill myself i would put a gun to my head not suffer from strangalation..
i forgot to add David Carradine(the old school kung fu guy) died this way
https://abcnews.go.com/Entertainment/story?id=7763422&page=1im guessing they get used to it.... and bust a nut and pass out with the rope still tied to their necks and die.
i really havent researched it...but my guess the hanging causes a adrenaline rush and you have a orgasm at the same time... like i said i havent put much research into it, but that seems to me the logical answer why they do it.
