Beat the #1 Killer

It's not salmonella. It's not Ebola. It's not the germs you pick up from the bathroom-door handle. It's not even cancer. The number one killer is arterial disease, including heart disease, and the great thing is that heart disease is a paper tiger -- you can defeat it. These four moves can get you started -- and make you look and feel younger in the process:

• Pump your heart. Do enough physical activity to burn between 3,500 and 6,500 calories a week (or roughly 500 to 950 a day). To meet that goal, you'll need about 60 minutes a day of exercise that gets your heart rate up (where you're sweating or out of breath by the end).
• Get happy. Negative emotions like anger and hostility raise blood pressure. And people with depression are four times more likely to have a heart attack.
• Eat away at your risk. When making your grocery list, follow this simple rule of thumb: Opt for foods with healthful fats, fiber, and good-for-you nutrients like flavonoids, vitamins, and minerals. And nix processed stuff as well as foods laden with saturated and trans fats, salt, sugar, and syrups.
• Schedule sleep. Less than 6 or more than 9 hours of sleep a night increases your risk of both heart attack and arterial aging. Make sleep as important to you as work or family.
