I read in today's paper that a common drug that costs 10p a day may enable some people to live 50% longer. They will be starting trials on 70 and 80 year olds. Personally I would not want to live that much longer, would you?
The country couldn't afford it! Either pensions are paid longer or we stay in jobs and that stops young people getting jobs. It is the natural order of things. Even those fit and with all faculties get tired and can't do the simple things they used to manage.
