Trying something new later in life, like competitive sports, business enterprises, or artistic endeavors, can dramatically increase both your quality of life and how long you live. Openness and curiosity correlate highly with good health and long life. People who are curious are more apt to challenge themselves intellectually and socially and reap the rewards of the mental calisthenics that result. They are also more likely to be interested and engaged, which makes them more fun to be around, and interacting with others socially is a good way to stay mentally agile and alert.
