Yeah, it's hard to say whether it's worth it or not. Human life is very vulnerable. It only seems that you are the master of the Universe. People confuse individual human life with collective human life.

On the other hand, much of human life goes as in gray monotonous everydayness.
And when you look back at those days they all collapse into nothing. A person only remembers those bright emotional moments when he feels like the master of the universe. )))
