Congratulations, Ken Brown. You won't regret being work free.
I retired 9 yr ago at age 57 after 30 yr with a major multi-national company. I enjoyed all but the last two years when I spent most of my time downsizing my part of the organization. This was very unpleasant and after determining that I could afford to retire, I did and have not missed work for one second. In fact I feel better nowadays than I ever have.
