If that happens, my job should be satisfying enough to keep working there until I'm 70 or more.
You are very lucky! My job changed so much over the 20 years I worked. I no longer enjoyed what my field became.
Besides, my wife wants me to keep a job just to keep me out of the house. We've been married 30 years, and part of that success is not living with each other 24x7.
😁 😀 😂 I'm not married but have lived with enough girlfriends to know that I don't want to live with anyone anymore.
