Heart disease is the leading killer of men and women. But if you're exercising like crazy to lower your risk, it might not matter much if you then go sit in an office.

In fact, people who don't exercise, but move around more during the day, can burn  more calories than those who run 35 miles a week but work a desk job (and then maybe watch some TV on the couch).

Other risk factors include smoking, obesity, high cholesterol and even anger.
