Most of the world’s oldest people have certain behavioral traits in common, including:

Staying socially connected Being conscientious Not worrying too much Remaining optimistic Laughing easily Living happily Acting extroverted.

Mark’s Daily Apple has the details on why these seven traits seem to help people live longer and how you can cultivate these behaviors if you want to add years to your life. For example, laughing easily reduces stress, helps your immune system and can otherwise influence positive health mentally and physically. Best of all, all you need to do to laugh more easily is watch more funny stuff on TV, try laughing yoga or just force a laugh, which can still give you the physical and mental benefits of a natural laugh.
