Walk the dogs and foster dogs around the block, in a park, individually or together. This can also be a couples or family activity by volunteering at a local rescue group or humane society. It's outdoors in fresh air so it clears the head and gets bodies moving. A favorite place is in the Metro Parks where there are wildflowers on wildflower trails in the spring and the rustle of crisp fallen leaves in the fall. I have a favorite path where a diabetic dog and I walked many years ago.
Drive a leg of a rescue transport getting dogs out of shelters and into rescues. Transports are often several legs and across several states. There is a group for nearly every major highway in the United States. It's a drive and it is also charity miles, so tax credit is involved for the mileage driven. You must be very organized to do this because the animals are literally travelling from death row to a new life. There is a book called Fifteen Legs about rescue transports.
File paperwork and organize so my house looks better.
Look at beautifully illustrated books on canning and preserving and read scrumptious recipes.
If I am having chicken, I might put mango chutney on it. Oh, I am making myself hungry!
Explore my city or a nearby one -- go to a museum, a greenhouse, a large library.
Genealogy -- interviewing those in the family oldest about their lives and who is related to whom in what way, then mapping it out in a family tree program. Getting them to identify who that is in those old pictures, and labelling them. (Far too many picture albums get dumped at thrift stores or in the trash because people don't seem to care where they came from or how their families came to put down roots where they are.) If you don't have pictures of the people, all you can ever wind up with is pictures of their headstones when and if you can find where they are buried.
Another thing that I do is go to a book I have called "Leslie Linsley's Weekend Decorating, 1,001 Quick Home Decorating Ideas, Tips and How-To's", and pick a project.
