That is where the difference between health care and medical care comes in. Medical care is what doctors can do for you. Health care includes what you do for yourself -- such as diet, exercise and lifestyle.
If a doctor arrives on the scene to find you wiped out by a drug overdose or shot through the heart by some of your rougher companions, there may not be much that he can do except sign the death certificate.
Even for things that take longer to do you in -- obesity, alcohol, cholesterol, tobacco -- doctors can tell you what to do or not do, but whether you follow their advice or not is what determines the outcome.
Americans tend to be more obese, consume more drugs and have more homicides. None of that is going to change with "universal health care" because it isn't health care. It is medical care.
When it comes to things where medical care itself makes the biggest difference -- cancer survival rates, for example -- Americans do much better than people in most other countries.
No one who compares medical care in this country with medical care in other countries is likely to want to switch. But those who cannot be bothered with the facts may help destroy the best medical care in the world by falling for political rhetoric.
