My Hubby and I did just that and had 17 wonderful years doing whatever.
I guess I could see it if you can start a business or do something hobby-wise....I know people that go part-time or even just do a second career in a kind of reduced capacity with more flexible time as a kind of early retirement. I do like that idea.
Sounds like you two have had a great time.
My dad’s been doing it for 29 years. Best thing he ever did. Mellowed him out and smoothed off the rough edges.
