Want to know the secrets to a long and happy life? These 10 tips will help you live longer and better.

Kick Bad Habits

Treat your body like it's going to last for 100 years. People who exercise and don't smoke are much healthier when they reach old age.

Volunteer

Studies have found senior citizens who volunteer are happier and healthier than those who don't. The same goes for younger people.

Drink Red Wine

It's good for your health -- as long as you don't overdo it.

Take Nootropics

Nootropics are supplements for your brain. They help you stay sharp. In spite of their funny sounding name, the science behind them is sound.

Enjoy the Cold

People who stay in colder environments when they get older (as opposed to moving south) tend to live longer.

Become a Vegetarian

Vegetarians are much less likely to get heart disease, the leading cause of death in the U.S.

Don't Supplement Vitamin D

You'll be better off if you get it from natural sources like fruits and vegetables.

Try to Remain Calm

Take up yoga or meditation. Studies have found people who remain calm live longer (and better) than those who don't.

Drink Boiled Greek Coffee

It's great for your heart.

Be Social

People with strong social ties live longer and better.
