This came up at yesterday's London meetup: activities for keeping oneself relatable to other human beings.

We were dissecting motives behind goals, and one of mine was maintaining interests that other people could relate to. I have more pedestrian interests, but they're the first to get dropped when my time is constrained (which it usually is), so if I end up meeting someone out in the wild, all I have to talk about is stuff like natural language parsing, utilitarian population ethics and patterns of conspicuous consumption.

Discussing it in a smaller group later, it turns out I'm not the only person who does this. It makes sense that insular, scholarly people of a sort found on LW may frequently find themselves withdrawn from common cultural ground with other people, so I thought I'd kick off a discussion on the subject.

What do you do to keep yourself relatable to other people?

EDIT: Just to clarify, this isn't a request for advice on how to talk to people. Please don't interpret it as such.
