Any tips on a pass time for my dad?

My dad is 77, and very very active, he rides his bike every day, does maintenance on his home ,gathers and chops his own fire wood, is out 4/5 nights a week at the casino or hotel lounge with my mum, and still entertains as a keyboard player. He lives a great life!
The problem is 3 weeks ago he fell off his ladder and broke 6 ribs at the back of his Left side. He has been in critical care & is now home, but he’s quite down as he isn’t really doing much. TV has never been his thing. I take him out to a cafe once or twice a week, but he’s bored. He should be up & about again in a month , but then he has a hip replacement op in January, so he’ll be house bound again for a couple of weeks. He isn’t a reader, and I just wish I could suggest something to keep him busy. He’s a get up and go man, who can’t do that right now.
Any suggestions?
