Retirement can be good provided you planned ahead. The reason I am working is a friend has opened a few retail mattress stores and ask me to work a couple of days a week. This week turned into 4 because someone is on vacation. Don't make a lot of cash, but all is good. My wife makes really good and that is what counts.
Lesson in life, marry a younger woman.
Just kidding, plan ahead for retirement and don't start planning when you're 50. Plan early and take advantage of any matching investment you can.
