Depressing Dip in Middle Age, Joy in the Golden Years

Middle age is miserable for many, according to a study using data from 80 countries showing that depression is most common among men and women in their 40s.

The British and U.S. researchers found that happiness for people in 72 countries ranging from Albania to Zimbabwe follows a U-shaped curve where life begins cheerful before turning tough during middle age and then returning to the joys of youth in the golden years.
