@Prof_Trixie This is *exactly* what I do in my social circles (and I, too, am 45). It's particularly something I enjoy in my roller derby league, since I've been involved in the sport since 2007 and roller derby today is like baseball at the turn of the 20th century...just starting to stabilize after a wild era of evolution. The younger people crave the history I hold in my head and I have the means to help them with things. It's...nice.
