I am 68 and never understand why people don't keep working if they love their job. I have been in the same line of work for 47 years and while I have slowed down due to age I still enjoy getting up every morning and working. Of course I mostly work from home and for myself so I don't have to answer to anyone. (other than my wife) I will work until my mind and body goes. What else am I going to do? I don't golf. My body won't let me play tennis anymore. Not interested in pickle ball. Go to work. Always something to do.
