The numbers are savage. In the United States, cardiovascular disease kills one of us every thirty-four seconds. Scientists at Tufts discovered that only 7 percent of Americans have “optimal cardiometabolic health.” Even the young are at increasing risk. About 30 percent of all heart attack patients today are between thirty-five and fifty-four years old. Now 40 percent of all people who die before turning seventy die of cardiovascular disease.
