Pattern comments on What are habits that a lot of people have and don’t tend to have ever questioned?

[Pattern]

I misread your question as being about beliefs, rather than habits. It’s harder to come up with habits rather than non-habits. (Buying lottery tickets is probably an action.* Not buying lottery tickets is more a non-action.)

*Subscription, and regular payment systems, mess with what is and isn’t an action.

For the low hanging fruit right now, I’d say “Hand shakes, and touching door knobs.”
