I don't know if people want to reopen this or let it lie - I just found it and wanted to comment.
So many issues play into choosing early retirement or not. Most of what was posted seems to apply more to men, although a few mentioned women's viewpoints.
I am in that transitional generation - women 10 years older were not expected to work after marriage, while those 10 years younger never questioned that they would work after marriage. We were the ones who shifted society's viewpoint (decent birth control methods helped a lot there). In that light, being able to work and being taken seriously at our jobs while we had husbands and children was almost seen as something we had to fight for, it wasn't just a given. We had to prove we were "worth" higher education. Again, those 10 years older were thought to be using that higher education for the benefit of their children, while we were using it for ourselves. So once all that effort went into education and a job, it was not lightly abandoned. Therefore, women old enough to remember that reality may not be as keen to retire, when a large chunk of society will not see them as retired, just as "homemakers back where they belong" - I know that is not many people here, but look around you.
Also, let's be real here, women generally live longer than men, although the gap is not as big as it used to be. My retirement funds have to probably last me at least another 30 years, based on family history. I hope to do some major spending (travel) in the next few years, then have lower financial needs while I am more of a homebody, then higher as I move into a probably more expensive lifestyle (senior's residences, assisted living). Since none of us can predict our future health no matter how healthy we are now and how good our family history is, all these are unknowns that we have to plan for, however vaguely.
