Why not just keep walking? It's great exercise.

Oh man, I would be worried about falls. Have you tried a VR headset? Could you go test one out? They make me seasick so there is no way this would work for me.

My husband and I are empty nesters, nearing sixty. Our evenings seem to consist of watching TV and the occasional dog walk. Wondering if gaming might get us more active and off the couch. Any recommendations on cost, equipment and getting started if you are an older person?
