It is like the way they constantly put the word 'vulnerable' in front of mentions of the old and elderly. In winter public information notices tell people to keep an eye on vulnerable elderly neighbours, with the inference that if people are old they are, by definition, vulnerable.
My DF lived to be 92 and could not possibly be described as vulnerable until the onset of his final illness and hospital admission, which was less than three months before he died. He was living in his own home without carers still active on the committees of three local organisations and happily driving a 100 miles or more to visit me or my sister. Shortly before his 92nd birthday he drove over to our house in France quite happily and well able to cope with driving on the other side of the road.
I think the problem is that older people are only in the news when they are vulnerable and oddly enough, the charities that so much to help those older people who do need help, do those of us who are going into old age fit, healthy and more than capable of running our own lives, a disservice by constantly harping on the problems older people have
But then we only hear about young people when they are unemployed, drunk, drugged or criminal, which does a disservice to all those young people who work hard, stay sober and off drugs and generally lead responsible lives.
