Congrats Ray, you wont regret it. I worked for two firms. One only for a year, the other till my boss retired, then self employed from 1983.
As Alan says, spare time will be at a premium. First your jokes MUST improve, no excuses now Second you will prepare a prize winning garden and finaly you will get to your boat, errr maybe not, you will have all the shopping to do !
Happy retirement !
