How to fund healthcare is a conundrum across the world due to an increasing number of old people who are often sick in complex ways. Solving it requires evidence based assessment of policy choices. That's difficult in the UK with the highly politicised debate about the NHS.

Depends on measuring system. The World Health Organisation puts UK #18, Ireland #19 (France tops, US is #37).
