The issue of someone living on his or her own at any age and becoming ill at home could lead to a situation of them not being found.
If, say, someone has a job in a friendly small enterprise and does not turn up for work then maybe someone telephones and if there is no answer goes to the person's home and knocks on the door. If there is no reply calling the police.
Yet if, say, someone who lives alone is out of work and does not arrive at the jobcentre to sign, then quite possibly all that hapoens is that the claim is closed and a P45 or whatever it is called now is sent by post.
It could happen to someone who is out and about every day.
I did read some time ago about a lady who had got stuck in her bath and was only rescued because a lady on the checkout at a small mini-supermarket noticed that the lady, who had habitually popped in everyday to get something, had not been for a couple of days. Had it been a large supermarket with many checkout lanes, would she have been rescued?
So it is easy to focus the concept on me, but it could apply to many people of whatever age who lives alone.
Even if one gets on well with one's neighbours, which it might surprise (and maybe annoy!) some here to know that I do, each family leads it own life, people only tend to come together if something kicks off, such as a conman about. They are neighbours, relations are cordial, but it is like people one knows at work, like, for example, a lady who works as a secretaey whom one might see around some days and just say hello in passing.
