Queen Elizabeth I's dying words are reputed to be 'All my possessions for one moment of time'. Famous last words in most cases should be taken with a pinch of salt, and like many others these are probably apocryphal.
However, assuming she said them, one can make a point about the trade off between health spending and life expectancy.
Most health spending is at the end of a patient's life, prolonging the inevitable for a period. It is of course entirely natural, like Elizaeth, that the patient should want this. Looking from a purely economic view at Elizabeth's statement, given that she was about to lose all her possessions anyway, and had no heir, with their value to her rapidly depeciating to zero, the supposed offer is a very rational one.
However, if when she ascended the throne at the age of 25 she had been asked if she wanted to give up her realm, powers and possessions in return for a moment longer on her death bed she would undoubtedly have refused.
Whatever trade off she would have made at that time, or anybody would make at various times in their life in terms of health insurance, with a nationalised system that is taken out of their hands. The state decides how much money to take off you, and how much it will spend on health care, and you only have the choice of liking it or lumping it.
