You could try reliving your life in increasing increments – start off reliving your last hours, then start back at a week before death, then a month… something of that sort. Although you might (if you go back far enough) be able to delay/hasten your death, so the time-unit thing wouldn’t be perfect.

Or just go to the extreme, reincarnate and have another go at the whole thing – I’m not so bothered by it not being the same life over again, that’s sort of the point from my perspective… to live it differently on each pbum and see what can happen.

Maybe if you chose how far back to jump each time… pick a point in your life to reinsert your older and wiser consciousness into.
