I just celebrated my 11th anniversary after retiring from NASA at the beginning of 2009. I've mixed feelings about the whole thing. On one hand was/is great to be around while some of the kids are still living at home. OTOH wish I would have given as much thought to WHAT EXACTLY I'd be doing with my retirement as I did to whether I could afford to retire. I'm the type to just waste time in the absence of any clearly defined activity. Oh well, it is what it is at this point. My latest 'activity during retirement is caring for my mid 90s parents who moved in with us a couple months ago. Not fun, but necessary.
