I thought he had a table of recommendations including things like living in cities, but I can't seem to find it skimming Black Swan, so perhaps I saw that in some of his writings since then.

Probably -- at some point Taleb was writing about optionality and how having some is a very good thing (you expose yourself to the volatility but cut off the left tail). Like you I don't remember the sources, but I think it was a few years after the Black Swan.
