Before you get out of bed to commune with the coffeemaker, take your pulse: Put two fingertips on your wrist or carotid artery (in your neck under your jaw) and count the beats per minute. This is your resting heart rate. Anything higher than 83 means you're at increased risk for a heart attack.
To slow your resting heart rate: The key, ironically, is to make your heart beat faster for an hour per week (to calculate your ideal number of beats per minute while exercising, subtract your age from 220, then multiply the result by 0.8). So, just as you'll be doing for healthy blood pressure, simply work up a good sweat.
