The Commission for Social Care Inspection has reported that more and more elderly people are relying on relatives as the population in the UK ages. In England alone, there are 4.7 million people over 18 who are unpaid carers for elderly or disabled people.
(It is alleged that this kind of care of the elderly in the UK saves the British state £57bn a year. I'm afraid, they'll have to look after me when I'm old and grey.)
