Barbara Hannah Grufferman: Seven Habits That Will Help You Live Longer (And Better)

'The study showed that following the recommended habits not only predicted lower mortality, but those who lived longer also suffered fewer disabilities. In a news release, Dr. Breslow said, "What was surprising to me was how these seven habits were so strongly predictive of mortality."

The "Seven Healthy Habits" -- as Dr. Breslow referred to his key tips -- are:

Don't smoke.
Drink moderately or don't drink at all.
Get a good night's sleep of seven or eight hours.
Exercise 30 minutes at a time, several times a week. Walking vigorously is a top choice.
Forget the scales. Eat moderately to maintain weight in relation to height.
Eat regularly, whether that's two meals a day, three or five. Whatever you do normally, keep it up because it's the regularity of life and moderation in eating, sleeping and exercising that makes all the difference.
Eat breakfast every day.
