Faith in medicine runs deep in America.
We spend more per person on health care than any other nation. Whether we eat
too much or exercise too little, whether we’re turning gray or feeling blue, we

But there is mounting evidence that each new dollar we devote to the current health care system brings small and diminishing returns to public health. Today the United States spends more than $4 500 per person per year on health care. Costa Rica spends less than $ 300. Yet life expectancy at birth is nearly identical in both countries. Despite the highly publicized" longevity revolution," life expectancy among the elderly in the United States is hardly improving.
