As long as you do not mind talking to strangers it is one solution.

I don't mind talking to strangers, but I would prefer to avoid being one of the things I dislike in my daily life—I don't know that anyone likes being cold-called—unless I've misunderstood you?

Or have you thought about being a tourist guide or curatorial position?

I have thought about being a tour guide enough to know I don't want to try it: I'm trying to avoid jobs that keep me on my feet for extended periods of time.

I have no prior museum experience, so I've never seen a curatorial position I could apply for. I appreciate your faith, though!
