All those younger persons who were not there when...
Plenty of things remind us of the past!! Songs, movies, even towns we haven't seen for 25 years...etc!
And old guys remember the Moonlandings !!
That's our advantage!
The advantage of past memories is that we can be nostalgic and emotional about good ones and laugh or make laugh about the embarassing ones.
And when we find an old friend, there's usually a lot to talk about and it's not boring because there's emulation.
