I just got diagnosed with early onset arthritis in my hands, wrists, and fingers. What are some hobbies would suit a person with my predicament?

Soccer/Football perhaps? But then again, that's more of a sport.

hiking is fun but you need an area with good trails or maybe astronomy thats pretty low key just make sure you get a small scope thats easy to move around you can even get computerized GOTO scopes that move to objects on thier own

T'ai Chi. Really helps the arthritis thing.
