I dunno. Yesterday at the Farmers Market, I was shopping for produce (salads) and had a conversation with 2 different women. The first offered advice on what to pick, and their health benefits. The second, in turn, was the recipient of my limited knowledge.

I live in San Francisco.

If those supposed health benefits aren't real or are misrepresented, which I would guess is likely, then that social interaction was a net negative for society.
