I'd also comment that, in general, even though I've had jobs with tenures that many HN readers would consider ridiculously long, I mostly settled into the decade +/- space outside of a couple (of short) "events" outliers. Even with making some changes along the way sometimes, that ended up my been-there/done-that range. Obviously people are different but that has been my experience.
