I retired on August 31st 2004 at the ripe old age of 55 with my 401K and a full 80 point pension and health insurance, etc. The company I worked for also paid me 3 years of salary and benefits to stay home at that age, and I haven't looked back. I finally had to start taking from my 401K this year due to the 70 & 1/2 rule so I double dipped and started taking social security also.
I'm now 70, almost 71. I and my wife both have our health and life is good. Playing is fun and so far I haven't gotten tired of doing it
