You may think the key to a happy, long life was hidden in a top secret book, but the truth is, there’s really no secret path to true happiness and longevity. These two things cannot be obtained by having your dream job (even dream spouse) or by getting to experience extraordinary things.

Based on research, true happiness and a long life can be obtained through a combination of just simple things and a positive approach in life. Some psychologists emphasize open-mindedness towards other people and a sense of resiliency.

Understanding the basics of good, happy and long life isn’t difficult – and there’s no need reading a long book for that.

Here are the 5 secrets!

1. Eat Healthy

Most centenarians in the world lead a very modest life. It reflects mainly on their diets, which are often plant-based such as whole grains, vegetables, legumes, nuts, fruits and seeds. Eating less is actually a good practice. A good example is the people in Okinawa, Japan and their culture of eating until you’re 80% full (hara hachi bu). Also, the old saying ‘Breakfast like king, lunch like queen, dine like a pauper’ is another insightful word to follow and practice.
