I took two psych classes in University. One was "Death and Dying". Perhaps a morbid class to take in your 20s, but it was a full class. The professor happened to be dying herself as she taught it. Very useful and enjoyable. It's one of the few textbooks I've kept since the long-ago graduation. A very useful course to take.
in one view, most everyone is dying, while they read this.. a colleague did some hospice volunteer work for a while, and I made sure to quietly mention to her that I found it commendable and important.
