Oct 2018 was the date for me. I did some light work limited to 3-4 hours a day, Mon-Fri (I was self employed) for another year after that, and I still might do a few little things for a quick buck or two once in a while, but mostly I'm just working on my own stuff. I really like telling people I won't do their stuff any more.
My wife retired before I did, life is good. I recommend everyone do it as soon as you can, don't fall for that "full retirement" BS. Retire while your health is good and you can enjoy it. Gene
