One thing you can do while still somewhat physically able, or perhaps with getting help from neighbors, is a large garden. Right now I'm living with my father, and we have some neighbors who moved here after Hostess died. They have a big garden, which my father and I help with in various ways; they get a lower cost of living, we get wonderfully fresh veggies.
