Congratulations sir! I envy you. At 55, I have seven to ten year left to go. I say seven to ten because some people are getting "called in"
shortly after turning 62 and are being offered packages. Sounds like you got a similar deal. And working part time at a bike shop.. I call that a huge win.
Cisco offered a buyout last year to persons who were fifty or over, and had at least ten years with the company.
