We all die. Some die as they haven't got clean water, others as they didn't get a tetanus jab, or malaria tablets. These interventions cost pence.

I personally think that the NHS should give the care it gives regardless of extras you might have decided to get; I don't think that the NHS should give out all new drugs unless they have been passed by NICE as at least then there is some appraisal based on value for money.
