I find it hard to have intellectually interesting conversations while walking.

I know a lot of people are exactly the opposite.

I find that I'm drawn, like a moth to flame, to novelty.

If I'm in a boring physical setting, all of the novelty to focus on is in the conversation, the intellectual dynamic in front of me.

When I'm out walking, especially around other people, I'm surrounded by lots of incidental environmental novelty that distracts me from the intellectual novelty.
