My father is 80 this year and still works 4-5 days a week. He was a commercial banker until he got a golden handshake at around 60. He retired for about 5 years but got bored and since then has been working as a book keeper / accountant for a small company. He is probably luckly, because his friend owns the business where he works, but I am impressed nonetheless.
