Imagine there were a disease that kills as many as 400,000 Americans a year -- more than the number who die from breast, lung, colon and prostate cancers combined. This disease is as insidious as AIDS, claiming its victims after decades of weakening their hearts, blowing holes in their arteries, suffocating their organs and grinding down their joints. You have a 1 in 5 chance of having this disease, and if you do, you will be blamed for developing it and publicly shunned. Now, imagine that your doctor doesn't know how to treat you. Are you worried yet?
