My BFF went to school to be a funeral director, where they learned how to embalm on donated cadavers. So when my BFF was dying, they arranged to have their body donated to a local medical university, kindof as a way of "giving back". The program didn't disclose exactly what the bodies would be used for, but they said many of them were used for medical training. Anyway, in both cases (embalming training and medical training) apparently "unusual" bodies are still useful. Also, it greatly reduced funeral expenses because the program provided free cremation afterwards.

So, people should still consider donating their bodies after death, someone will probably find some value in it.
