Good for her. One of the things I've enjoyed doing since I retired in 2017 is taking once weekly courses given through a group of largely volunteer educators called Davidson Learns. They started out as in person classes and now have transformed into Zoom learning. Took one on health care issues looking at how health care is delivered in a number of other countries, one on the history of the electoral college, one on the Spanish Civil War and just finished one on a series of lectures on foreign policy releated topics such as China trade policy, Brexit, Russian foreign policy etc. Many of the courses are led by professors from Davidson College but also from other professionals. Like to think it keeps my aging brain from deteriorating as quickly lol.

I have a buddy, older, now maybe 80, a West Point grad, special forces Viet Nam, worked with me at an aviation company for a while. He kept on going back to college part time nights, mostly NYU to get other degrees on top of his West Point engineering degree...finance...Japanese and Russian language.....and a different engineering degree, he did it to keep his mind sharp. It worked he is the youngest looking and feeling 80 year old I ever met. Has the outlook of someone 20 years younger.
BTW, Davidson profs must be outstanding, that is one of the best small colleges in the country.
