I'm 66. I first retired at age 59 from a tech job with great benefits and healthcare for life. Got bored out of my mind, and went back to work at another tech company. Retired last July. By October I was again ready to work and am now working in yet another tech company. I have no idea how long I will live, and I do intend to retire when my wife reaches 65. Some of you make it sound terrible that someone is working at age 66. I am really happy working. (I could get by without working, but it is very nice to have an income stream)
