I work with older and disabled people these days. One of the most useful tools we have to keep people independent yet safe is called Lifeline, a button people can press to talk to someone immediately who will call out whatever service is needed if you have fallen, or feel ill or whatever. The requirement is that you have at least two people on the list who can be called for less than emergency situations, a friend, a child, a neighbour. Someone who will come and check you are okay when an ambulance is overkill.

If you knew how many people I visit who can't name two people who would come, or even care...
