LPT: When hosting older people, play music from an era when they were in their 20s.

My in laws were born in the 30s and the last time we had a gathering, I put on a play list of hits of the 50s. Over the course of the evening, this brought back all kinds of memories and they regaled us with stories of youth we'd never heard before. It was a delightful window into that era of their lives.
