My dad lives alone now. His is 75 and pretty sharp in the mind but has physical limitations. He struggles with activity. His doctor wants him to be more active and he still drives to his rehab for exercise. I've read about systems that help monitor and notify when the elderly have changes in activity or symptoms of change. Or, in the case of my dad, someone who will say he is going to the rehab but doesn't. Is there a monitoring product or service that I can use to help me track his movement and what he is doing during the day?
If you are really worried call him every day. Have a person you can call, a relative, friend of your Dad, who will check up on your Dad, if he doesn't answer. Tip his mailman, and ask him to call you if your Dad's mail builds up.
