Work on photo albums
Many of our elders have an enormous amount of photos from their past. You can suggest that they organize them in an album, and maybe also add some decoration (like a scrapbook) or notes to each photo, including anecdotes or comments about the people and events in the photos. This will help them remember good times, exercise their memory, and keep busy for a long time, and will be a nice piece of history for their family to have when they are gone.
