Government intervention in a sphere of life is rarely desirable and the UK's National Health Service is an excellent example. (My take: completely separate commissioning/procurement of health services from provision. Argue about the role of the state in the former and accept the manifest obviousness of the need for private responsibility for the latter).
However, every so often, something good comes out of it. Browsing for information on something completely different, I discovered the NLH Question Answering Service.
It appears to be a beta but for the even mildly hypochondriac, there is a lifetime's worth of diseases to worry about. Excellent :-)
