A recent study of 1,000 people aged 65-85 points to the importance of a positive attitude in dealing with life. After almost 10 years of follow-up, researchers found that people who described themselves as optimistic had a 55 percent lower risk of death from all causes and a 23 percent lower risk of heart-related death.

Optimistic people tend to be more physically active, drink less, and smoke less. They cope with stress more effectively.

While one's attitude toward life isn't everything, it does make a crucial difference in dealing with life. And who has more reason for optimism than Christians?
