kirbygirl I record everything I watch on tv so I can just FF the adverts, and in the evenings when I'm stuck at home with only the tv and the computer for company, I tend to be playing word games on the computer if a programme doesn't need my full attention and I can just listen to it.
I couldn't possibly be ironing or beautifying myself every night like some posters lol.. and knitting and crocheting is out for me, because like you I have arthritis in my hands. I also spend time on forums, and uploading photos, and playing around with photo editing sites.
You can also play games like Hidden object or similar games online. I like to play trivial pursuit of quiz games.
What about a Jigsaw puzzle, can you manage that? You could have it on the coffee table and do it while watching tv, and the push it away under the sofa or bed half done on a board when you get tired of it, and pull it out again when you want to continue.
