That article doesn't actually back up your claim. ("The waiting lines in the UK for surgeries make it more likely you die before you get it in time if you have anything remotely serious.")

At best, it has a speculative quote or two.

Here's a little tip, when trying to find a source for some BS about the NHS, try not linking to the daily fail, who are well known for printing mistruths and on occasion, outright made up stories about things like the NHS.

They reference their numbers from several other organizations, so I'd put a little more weight in that article than in usual daily mail stuff.
