The thought came to mind in noticing a lot of famous actors, actresses, other so-called celebrities, and major corporate executives who have been killed in some weird unexplainable incidents, like something went wrong during a simple surgical procedure(Joan Rivers), or they hung themselves from a doorknob under four feet from the ground with a red scarf.
My belief is that most people that commit suicides that they plan on going through with, end it quick, like hang from a closet bar, or a garage beam, running the car in the garage with the doors closed and windows open or a eat a gun, so all of these relatively recent death just may be no accident. Just some conjecture on my part, I wouldn't lay down a bet on it, because I have no proof, just patterns I see.
