I don't know how many people have this issue, but I can't read Choose Your Own Adventure books without marking several past pages so I can rewind time, or try multiple branches, or safely find out what was hidden behind the venomous Venusian potted plant. Really, the only bound on it is that I eventually run out of fingers to mark my place, which constrains my time travel abilities to about four save-states. (In visual novels it's even worse, since there are enough actual save states that saving at anything that looks like a potentially significant branching point becomes viable. I've actually started using walkthroughs from GameFAQs to find out where I don't need to save, so I can stop fretting about making an irreversible decision. Trivial time travel is surprisingly addictive! What would the world be like if everyone could do it, I wonder?)

I really, really wish that this were a useful approach to life, but if it's possible to save and restore universe states, I have not been made aware of this. And obviously I haven't noticed anybody else doing it.
