Klaus mentioned birdwatching, which is a great hobby that I am still able to do.

I was into birding for some years before my accident, and even though there are very few things I can do without aggravating my symptoms, birding is something I can still do. I have to impose some limits, and looking through binoculars too much is tough on my eyes.

You can also learn to ID birds by ear, which is really fun for me. There are a number of CDs for learning bird songs, and a few websites as well. The problem is that birds only sing for a few months each year.

Birding is also a good way to meet people, even if you're uncomfortable around strangers, as I am. Learning to ID birds by sight and sound is fun and might be good exercise for the memory, though it also could be too much info and stimulation.

I also listen to a lot of audiobooks and podcasts, and spend a lot of time meditating and stretching. I try to go for walks as tolerated, and as weather permits (it's not usually very cooperative in January in MN).
