What's the fastest way to age an artery? Subject it to high blood pressure, which will harden it like a garden hose that's been left out in the sun. A range of 120/80 to 130/85 mmHg is considered below the hypertension point, but it's not ideal. In fact, reducing your blood pressure from 130/85 to 115/76 can make your body up to ten years younger. There's no data to show that using drugs to lower blood pressure offers the full youth effect. So for now, you guessed it: Exercise, lose weight, reduce stress. The good news is the benefits from doing physical activity are just about instantaneous.
