I think all these big celebreties create their death, when they get bored of acheiving or trying to acheive or when the expectations of people around them, most of whom are just faces in a crowd, become too high and hinders the way they want to live life.
Example: Rajiv gandhi
Kennedy Junior
and a lot of small Businessmen and stars who fake cheat death, just so that they can live their life the way they want?
Implausible, yeah, I felt so too, just when I was writing it :-)
