maybe he could get one of those LifeLine (sp?) services. He would wear a button on a cord around his neck and press it if he needed help. The monitoring service talks to him through a tabletop unit that’s connected to a phone line and can send help if needed. My dad uses one of these, and it’s a tremendous load off my mind to know that he could summon help if something happened. His service is set up through the Visiting Nurses Association in his city. I believe the service costs around $25/month.
Reading later messages — Kathryn, maybe this would help your parents as well?
