I imagine going back to college to take classes as a retiree in 15 years and listening to the prof tell me what a dictator Trump was just so I can tell him how full of BS he is and explain what really went on to the kids around me. I'll gladly take the F.
I went back to graduate school in my 40s for MA US History. I was older than all the students and professors, except for one prof.
They were all super bright, but they had no common sense or larger perspective.
I had to remind them every week that “the devil is wise not because he is smart but because he is old.”
It was all quite fun.
