"One of the main arguments used to justify major reform of the NHS is the potential cost of an ageing population. The United Kingdom is not alone; the number of people aged over 65 in the European Union will almost double over the next 50 years,1 and there will be only two people of “working age” for each person over 65 compared with four today. It is estimated that this could cost EU countries as much as 15-40% on top of current expenditure to maintain existing health services." (Quoted from article)
