A new study has found that people who feel older than their true biological age have a 41 percent greater risk of dying than those who feel younger than their age. Finally, a reward for being immature (I will never stop feeling 19).

A recent British study yielded results that showed seniors who said they felt three or more years younger than their actual age had a lower death rate over the course of eight years then people who felt their age or older.

5 percent of the participants felt more than a year older than their true age, meanwhile, more than two-thirds felt three or more years younger than their age. Around 25 percent felt their actual age.

James Maddux, a professor emeritus of psychology and senior scholar at the Center for the Advancement of Well-Being at George Mason University, in Fairfax, Va told HealthDay, a health news provider, that optimism can be a powerful trait to help you live longer.

"Optimism in many ways is a self-fulfilling prophecy," he said. "If you feel your life and your health is largely under your control, and you believe you are capable of doing things like managing stress, eating right and exercising, then you are more likely to do those things."

How old do you feel? What tricks do you have to stay feeling young?
