what is the easy way to die

ok i hope you don't but my friend didn't try to kill himself it was just a experiment he wanted to try. he choked himself and breathed slower everytime he put pressure on his neck. and i don't know why you want to know the easiest way to die just a little weird. i don't know the quickest way to die but i know a few ways. but i don't feel comptable telling you anymore. well have a happy my lot day.
