PHILADELPHIA (CBS) – We are a nation of worry warts… we worry about our families, our money, our futures. We even worry about how much we worry.

One of the most subjects of worry is our health and we worry about our health, despite the fact it is bad for our health.

A recent study found that 37% of people worried about cancer as their top health concern, 14% heart disease, 13% obesity, 11% terrorism.
