First draft of calculating the chances of a middle aged man (me!) living forever is now live and is giving a reasonable 1 in 10 chance of survival. By the time I'm 120 technology should have improved so that I can pretty much choose what physiological age I want my body to be and then its just accidents and disasters I'll need to avoid - but with everybody having personal protection robots tuned into sensors monitoring every movement on the plane, "accident" could be a word of the past.
