My mother is 80, has hurt back, in terrible pain. Has twice called an ambulance because she can't stand the pain. The most recent time, I was due to call her, couldn't get her on landline or mobile (because she was in fact in A+E). I don't live in the UK, am only child, no relatives...so I end up calling the police. Finally find where she is, but then spend the best part of 24 hours finding out what is going on. Finally talk to her and she says "oh, I should have brought the mobile phone, but didn't think of it"....Aaargh...she is able to use it, to text (at 3 in the morning!). All this hassle could have been avoided if she had used the bloody thing...
