Moving every 2-5 years sounds like one of the rings of Hell from Dante.

Moving is no fun at all (and also costs money! deposits, movers and the rest of it), but the only thing worse is staying in one place. I just can't do it.

I mean, of course I tell myself this is the last time we're ever moving, and that this is the forever spot. However, experience suggests this is never, ever the case, and there's no actual precedent for that.
