Blood Pressure: 115/75
Hypertension is a cunning thief; left unchallenged, it can steal a decade of quality life. The average American's blood pressure in middle age is about 130/80, but since the average American dies of heart disease, that number isn't good enough. Instead, aim for 115/75. Measure your blood pressure monthly at the same time of day with a home monitor or one at a local drugstore.

To lower blood pressure: Exercise hard enough to sweat for at least an hour each week. If you're used to 30-minute workouts, this means you'll need to do three, since it takes at least 10 minutes to start sweating.
