It is said that in England death is pressing, in Canada inevitable and in California optional. Small wonder, Americans life expectancy has nearly doubled over the past century. Failing hips can be replaced, clinical depression controlled, cataracts removed in a 30 minutes surgical procedure. Such advances offer the aging population a quality of life that was unimaginable when I entered medicine 50 years ago. But not even a great health-care system can cure death-and our failure to confront that reality now threatens this greatness of ours. Death is normal; we are genetically programmed to disintegrate and perish, even under ideal conditions. We all understand that at some level, yet as medical consumers, we treat death as a problem to be solved. Shielded by third--party payers from the cost of our care, we demand everything that call possibly be done for us, even if it’’s useless. The most obvious example is late--stage cancer care: Physicians-- frustrated by their inability to cure the disease and fearing loss of hope in the patient--too often offer aggressive treatment far beyond what is scientifically justified. In 1950, the U.S. spent $12.7 billion on health care. In 2002, the cost will be $1540 billion. Anyone can see this trend is unsustainable. Yet few seem willing to try to reverse it. Some scholars conclude that a government with finite resources should simply stop paying for medical care that sustains life beyond a certain age--say 83 or so. Former Colorado governor Richard Lamm has been quoted as saying that the old and infirm "have a duty to die and get out of the way", so that younger healthier people can realize their potential. I would not go that far. Energetic people now routinely work through their 60s and beyond, and remain dazzlingly productive. At 78, Viacom chairman Sumner Redstone jokingly claims to be 53. Supreme Court Justice Sandra Day O’Connor is in her 70s, and former surgeon general C. Everett Koop chairs an Internet start-up in his 80s. These leaders are living proof that prevention works and that we can manage the health problems that come naturally with age. As a mere 68-year old, I wish to age as productively as they have. Yet there are limits to what a society can spend in this pursuit. As a physician, I know the most costly and dramatic measures may be ineffective and painful. I also know that people in Japan and Sweden, countries that spend far less on medical care, have achieved longer, healthier lives than we have. As a nation, we may be over funding the quest for unlikely cures while under funding research on humbler therapies that could improve people’’s lives.
A．Americans are better prepared for death than other peopleB．Americans enjoy a higher life quality than ever beforeC．Americans are over-confident of their medical technologyD．Americans take a vain pride in their long life expectancy
