Found this little number, based on a Pew Research Center study, enlightening:
Turns out that, even though a majority of those surveyed believe that they'll have to continue working even after they retire ("Hello, welcome to Wal-Mart!"), it may not be so. Apparently, only a bit more than 10% of retired folks currently work outside the home (either full- or part-time).
Our goals about when we'll retire seem a bit unrealistic, however: although the Average Joe (sorry, Joe!) believes he'll retire at about 61, folks are actually retiring (on average) at the ripe old age of 58. Who knew?
Most surprising (but pleasantly so) was the finding that -- 2 to 1 -- the folks who think they'll be working post-retirement expect it'll be because they want to, not because they have to.
