How to live longer

MSNBC has an article from Forbes on 10 ways for you to extend your life. Some of them seems quite fun to do, like "Have more sex". Others are quite sensible, like "Stop smoking". These are supposedly based on research and I've reproduced them here if you decide to try them out.

1. Don't oversleep
2. Be optimistic
3. Have more sex
4. Get a pet
5. Get a VAP
6. Be rich
7. Stop smoking
8. Chill out
9. Eat your antioxidants
10. Marry well
