Who do you think it would be? It doesn't matter what the circumstances were or are, if he is was/is bad or good person, or even deserved the incredible life he experienced.
I want your opinion on what man, in all of world history up to now, from birth to death (or present if still alive) has had who you feel to be the best, most fortunate, lucky, incredible, wonderful, remarkable - whatever you want to call it - life.
