When I retired four years ago (May 1, 2007) folks I spoke to wondered how/why I would retire at such an "early age" (heck, I was already old, at age 59).
Today, being a bit older (and SS age) nobody ever asks the question. Heck, I go to Kohl's (department store) on Wednesday to get their "senior discount" and they give it to me without having to mention it.
I'm not complaining - life is good...
