Good news: turns out a glass half full is more than enough to sustain your health, heart and salary for years to come. Here's why it's high time to crack a smileOptimist

" Always look on the bright side of life." Believe it or not, Monty Python offered up some of the best health advice of the 10th century. Research shows that optimists live longer, are richer and are mentally stronger than pessimists. They have lower stress levels and better immune systems. They get more exercise
and eat more healthily. One 10-year study found that optimists were 23% less likely to die from heart disease and 55% less likely to die prematurely from all

causes. It's tempting to think that these bright-eyed fools are setting themselves up for one fall after another. But, on average, they earn 20k more a year than negative thinkers. And studies show that pessimists feel just as bad when things go wrong - the only difference is that the optimist concludes that next time things will be better. Chances are, they will be. So turn the page to tap into the powerof positive thinking.
