Maybe you'll make different decisions and things turn out differebtly in the next occurence?
There might be something to this, actually.
Assume that Poincaré recurrence applies to the universe. This doesn't necessarily mean that everything will always happen identically - it could mean that reality repeats itself
to the nearest possible degree endlessly. That could effectively mean that history will play out identically to the point of my birth each time, but that, for me, my actions and choices will differ each time, just as they will for you. The basic facts, up to the point of your birth, play out identically,and from there everything is subject to change. And it will be this way forever.
I am, actually, convinced that this is what it is. Which could be very cool for me actually- I was a very happy boy up until my father committed suicide, aged six.
If what I'm saying is true, the odds are strong that, on the next iteration, he won't kill himself; that was basically a freak event that turned me into a massively antisocial sociopath. I was extremely happy as a small child. I think, if he lives, I will become an extremely happy young adult also.
I am totally down with rolling the dice on this being the case.
