18. Have a happy marriage

Married people tend to have better health than unmarried people. For instance, married individuals tend to be able to have lower rates of alcoholism than their unmarried counterparts because they tend to offer encouragement, support, and protection from daily problems. They are also more able to handle stress better as a result. However, studies suggest that divorcing then remarrying actually increases the risk of dying prematurely.

19. Be optimistic

People with a positive outlook on life can actually live longer. Researchers found that optimistic people decreased their risk of early death by 50 per cent compared with those who leaned more towards pessimism.

20. Eat chocolate

Chocolate contains flavanoids and antioxidants which have positive health benefits. Flavanoids aid cardiovascular health, while antioxidants are believed to prevent or delay certain damage to the body’s cells and tissues. Dark chocolate is considered best as it contains more than twice as many antioxidants as a bar of milk chocolate, and has fewer calories.
