Most Americans will live into their late 70s. But, an increasing number of people are reaching age 100 and beyond. In the US, there were about 55,000 centenarians, according to a report issued in April 2014. That number is expected to grow.

One great way to become a centenarian is to study people who have enjoyed exceptionally long lives. That is exactly what researchers at Boston University’s School of Medicine have been doing since 1994.

These researchers have discovered many interesting findings that give clues as to what it takes to reach the grand age of 100 and beyond. You may be wondering if you share any traits with these centenarians, For each question that you can answer yes to, give yourself one point.

Are You a Woman?

The New England Centenarian Study has found that the majority of people age 100 and older are women. The bright spot for men is that those who do reach centenarian status are generally healthy and fit, since they have been able to avoid the kinds of diseases that usually affect older people. Researchers also found that woman who were able to have a baby naturally at age 40 or older were more likely to live to be beyond 100, possibly indicating that their bodies may age more slowly than others do.

Do You Have a Healthy Weight?

There is a lot of evidence that obesity is linked to serious and life-threatening health problems, like heart failure and stroke. Many people who live to be 100, especially men, are slim.

Are You a Non-smoker?

Smoking can also increase your risk of developing a range of diseases, like chronic obstructive pulmonary disease (COPD), heart disease, and cancer. Not surprisingly, centenarians did not smoke or smoked very little in their lifetimes.

Do You Handle Stress Well?

Centenarians possess strategies for dealing with stressful events in a healthy way. Having good coping skills may add years to your life. Stress is linked to chronic health conditions like depression, anxiety, and high blood pressure.

Are You an Extrovert?

Some characteristics of an extroverted style include getting a lot of enjoyment from being around people, having an optimistic attitude, and being less cautious in new situations. Centenarians leaned more toward extroversion than neuroticism (experiencing a lot of negative emotions, like anxiety and fearfulness).

Do You Have Close Relatives Who Have Lived Exceptionally Long?

Your grandparents, parents, and older siblings may give you a glimpse as to what your life expectancy might be. There may be genetic factors—longevity genes—that contribute to being a part of the centenarian club.

Increase Your Score and Your Age

You can improve your odds with these tips for a longer and healthier life:

• Take care of your health. If you have a family history of chronic conditions, like heart disease, work with your doctor. Find out what you can do to lower your risk, like making lifestyle changes or taking medicine.
• Avoid smoking. If you are currently a smoker, ask your doctor for strategies to quit.
• If you drink alcohol, only drink in moderation. This means 1 drink per day for a woman and 2 drinks for a man. There is some evidence that moderate alcohol use may ward off dementia. Heavy drinking, on the other hand, can lead to liver damage and other physical and mental health conditions. If you choose not to drink, that is okay too. You do not have to start drinking to achieve health benefits.
• Handle stress more effectively. By working with a therapist, you can learn coping strategies and relaxation techniques that can make difficult times easier to get through.
• Let your extroverted side come out to play. Socializing with friends and family and adopting an optimist attitude may help you live longer and enjoy each day more.
• Eat a healthful diet. Adopting the Mediterranean diet, with its emphasis on plant-based foods and olive oil may help to reduce your risk of cognitive impairment. Eating more fish may also offer benefits.
• Exercise regularly. Beyond lowering your risk of obesity, heart disease, and diabetes, being physically active may also improve the way your brain works and decrease your risk of cognitive impairment.
• Keep your brain busy. There is some evidence you can keep cognitive impairment at bay by challenging your brain. Engage in activities that you find mentally stimulating, and try learning something new!

By staying healthy and active, it is possible to get the most out of your life when you reach age 90 and beyond.

The secret to a long life may be to take good care of yourself and do what you love.
