The NHS has a lot of things going for it. It caught my mum's lung cancer very early, as a result of which, she's still here. [She'd gone in for something different, and the doctor sent her for a chest x ray because he thought she sounded not very good]
There are some, indeed, quite a lot of things it does brilliantly.
There are some that are patchy - the whole 'postcode lottery' thing isn't a myth unfortunately, and alas, there are some things that it doesn't handle well.
MyTimeNow, Sasha, I'm glad that you have had positive experiences. Most of the people I have encountered... have not been so fortunate. But that's in a different time and a different place.
