This, by Cristina Odone, is quite interesting.
"Britons cannot make up their mind whether they are submissive victims who must be looked after by a benevolent State; or self-reliant patients who make calculated lifestyle choices (and pay for them — whether they be the yoga class or the nicotine chewing gum) in order to stay healthy."
I think her basic premise is right. Adults all have to take an active, informed responsibility for our own health, we have to recognise that there are consequences arising out of behaviours that imperil our health, and that if we are given advice and offered help by the NHS to manage these risks, and we fail to act on that advice, then we cannot reasonably expect the NHS to give us the same priority as others who do take that advice.
That's the grown up approach - children and adolescents get told what to do but adults get to make choices and need to live with the consequences.
Some good points have been made about people living with impairments that make it harder to exercise, which I think is fair enough. The advice and support should correspond with the individual situation.
But in general, it is fair to expect grown ups to follow advice to lose weight by managing their eating and taking exercise before they get the hip replacement or whatever. They should expect to lose priority for surgery if they don't respond to the other part of the holistic package of treatment - the part that relies on them taking personal responsibility and demonstrating a serious commitment to their own continuing mobility and health.
OK, I am going to bring the car into work today but I'll be good next week, honest!
