Would just like to share this with everyone because as much as I know this isn't a new idea as such, it has been very much improved. I picked up a leaflet in sainsburys today about a new mobile care service from O2 health. It says if your medical condition affects your confidence doing day to day things, help at hand could be for you. Another good feature is that if the handset detects you've had a fall it can automatically call for help. Greater reassurance for the family when needing to go out!
