I was a long time high school teacher and loved my work, but then the private therapeutic school where I taught closed, and once you have a lot of years in a new employer has to pay you for that, or hire a kid right out of college at the minimum. Also, if the director or principal of a school is younger than you are, forget a job there. In any case, now I am doing a skilled blue collar job in my sixties, and I like it enough that I plan on doing it until they push me out or I drop dead on the worksite. Of course I had the valuable skills before I got my present job, and there was no expiration date on them. An advantage to physical work is that as we age we need to move more than ever, and I feel really good and sleep like a rock every night.

I am curious about one thing in your case though professor. You have obviously had a very productive career, so do you ever have the feeling that you need to step aside and let a younger academic take over your position? I don't know if your field has a lot of under employed PhDs, but when we say we are concerned for future generations it seems like stepping aside so that one of them can pursue the professional career that they prepared for would be a practical thing we could do for them in the here and now. A younger professor might also be more comfortable with remote learning and do a better job with it than you are doing. Like I said, I'm hanging on to my job as long as they'll have me, so I have no intention of training a replacement and stepping aside either. The more indispensible I am the more I like it, but anyone can be replaced.
