I was just reading an article about ageing, and how it all means we're going to have to give up beer, not just for the effect on our arteries, but also because we'll have to save half our income just to eat in our dotage.
Then a perhaps more interesting (read less mathematically involved) question struck me.
Hypothesis 1: Mankind is too short lived to achieve real wisdom, or plan sensibly for the future because we're already dead by the time it gets here. (John Wyndham)
Hypothesis 2: Through the course of life opportunities naturally occur for making immoral decisions and acts. Extend the timeline far enough, and one could expect all persons to have done some absolutely ghastly things. In short, your only hope of dying without sin is to die before you are propositioned by [censored].
Thoughts?
