You can chart the evolution of a generation by what information its members swap when they get together.

In my twenties, my friends and I would discuss restaurants, sharing new places we had found. Our thirties have seen a dramatic shift in the discussion to reliable contractors and mechanics. The forties will undoubtedly bring a sudden surge of proctology recommendations. And our fifties: estate planners.

When we all hit sixty, I hope to God we to back to restaurants. Because I don't think I can spend ten years talking about Winnebago dealerships.
