How long we live is usually dictated by our genetics. But a recent study found that four bad habits – smoking, drinking too much alcohol, not exercising, and not eating enough fruits and vegetables – can age us by as much as 12 years. No kidding!

Fortunately, there’s a lot you can do to prevent sending yourself to an early grave. In fact, making a few small changes to your lifestyle right now can have a major impact on how long you live. Here are five habits that will keep your body feeling young and looking good for many years to come.

Don’t overeat

To slow the aging process, you may want to leave some food on your plate. Research has found that the oldest Japanese people stop eating once they feel about 80 percent full. Try to avoid saturated fats and eat a diet full of unprocessed fruits and veggies.

Get adequate exercise

Turn off the TV! Many studies link a lack of physical activity with weight gain and a shorter lifespan. Aim to get at least 30 minutes of moderate exercise every day to lower your risk of heart problems and help you live a long, healthy life.

Maintain a social network

A study from Brigham Young University showed that keeping in touch with friends and family can help you live longer. Being engaged in a community not only prevents loneliness, but also promotes healthy behaviors like exercising and eating well.

Drink in moderation

Excessive drinking can lead to all sorts of health issues ranging from weight gain to liver problems. But when consumed in smaller quantities, alcohol can actually be good for you. If you’re going to drink alcohol, consume no more than one drink per day for women and two drinks per day for men to live a healthy life.

Quit smoking

A study published in the American Journal of Public Health found that women who quit smoking by age 35 add as much as six to eight years to their lives. However, it’s never too late to kick the habit. Quitting smoking can your increase survival odds even if you’ve already caused significant damage to your lungs.
