Too many variables. Am I missing every other day as myself? Because that changes a lot if I have to explain why I'm disappearing every other day. Is someone else being me during that time? That could suck. Also who am I becoming during my times away from me. Provided they're not someone being held in some kind of terrible living situation it could be refreshing to see what another life is like... but it wouldn't be terribly nice to spend every other day as a homeless vagrant... or someone wasting away in prison.... or worse.
So yeah... question unanswerable without further details. If this was how it was presented to me by some kind of bizarre genie or something, I would decline. It's too vaguely worded and there are FAR too many ways for it to go horribly awry.
