10 health habits that will help you live to 100

1. Don't retire.
Volunteer as a docent at your local art museum or join the Experience Corps , a program offered in 19 cities that places senior volunteers in urban public elementary schools for about 15 hours a week.

2. Floss every day.
Research has shown that those who have high amounts of bacteria in their mouth are more likely to have thickening in their arteries, another sign of heart disease.

3. Move around.
Study after study has documented the benefits of exercise to improve your mood, mental acuity, balance, muscle mass, and bones.

4. Eat a fiber-rich cereal for breakfast.
Getting a serving of whole-grains, especially in the morning, appears to help older folks maintain stable blood sugar levels throughout the day, according to a recent study.

5. Get at least six hours of shut-eye.
Instead of skimping on sleep to add more hours to your day, get more to add years to your life.

6. Consume whole foods, not supplements.
Strong evidence suggests that people who have high blood levels of certain nutrients--selenium, beta-carotene, vitamins C and E--age much better and have a slower rate of cognitive decline. Unfortunately, there's no evidence that taking pills with these nutrients provides those antiaging benefits.

7. Be less neurotic.
Find better ways to manage when you're stressed: Yoga, exercise, meditation, tai chi, or just deep breathing for a few moments are all good.

8. Live like a Seventh Day Adventist.
Followers typically stick to a vegetarian diet based on fruits, vegetables, beans, and nuts, and get plenty of exercise. They're also very focused on family and community.

9. Be a creature of habit.
Centenarians tend to live by strict routines, eating the same kind of diet and doing the same kinds of activities their whole lives. Going to bed and waking up at the same time each day is another good habit to keep your body in the steady equilibrium that can be easily disrupted as you get on in years.

10. Stay connected.
Having regular social contacts with friends and loved ones is key to avoiding depression, which can lead to premature death, something that's particularly prevalent in elderly widows and widowers.
