Five Ways to Live to 100

When you're watching The Today Show and Al Roker starts sending out birthday greetings to all the centenarians out there, you're always tempted to call those folks up and ask how they made it to 100.

3. Make time for tea. Green, Earl Grey, chamomile, take your pick – the flavor doesn't matter. All teas contain flavonoids, which relax blood vessels and thin the blood, reducing your risk of heart disease.

4. Spend more time at the water cooler. By making friends at work, you can reduce your heart rate and blood pressure – a major bonus during stressful situations that might otherwise cause a stroke or heart attack.

5. Fall in love. When you've got someone special in your life, your body's happy, too: In a study, scientists found that happily married men had healthier hearts than their bachelor brothers
