Pessimism has been linked to a higher risk of dying before age 65, while expressing positive emotions, such as optimism, is associated with lowered production of the stress hormone cortisol, better immune function, and reduced risk of chronic diseases. If you're a pessimist - or know someone who is - try the following:
Take care of yourself by eating a healthy diet, exercising regularly and getting adequate sleep.
Express your emotional reactions honestly so you can effectively deal with what's bothering you.
Confide in someone - your mate, a good friend or a trusted relative.
