I kinda imagine all the tiny decisions and how they affect everything, from the not-very-important to the stuff that I think really affects things.. actually I think I did that since seeing red dwarf when the multiple dimensions thing was brought up

Its really interesting to think how many different outcomes there could be, but yeah like Ouch! said I don't ponder it that much because it is kinda related to regretting things and wondering if you could change things and thats usually just pointless and upsets you when its too late anyway
