I'm laughing at the image of my T and I trying to do therapy on the floor. He and I both have nagging back issues and I can imagine it would take us both about 30 minutes to get back up. In fact, we might would both need the emergency button they advertise on TV to call the secretary to help us up. You know the commercials: "Help! I've fallen and I can't get up." Yup. That'd be the case.
