Last December, government researchers reported a big increase in suicides among middle-aged people in the United States. They looked at injury-related death rates by age group from nineteen ninety-nine to two thousand four. They found that suicide increased almost twenty percent among people ages forty-five to fifty-four. No one is sure why.

By comparison, rates generally fell for those sixty-five and older. And for people twenty to twenty-nine the suicide rate was nearly unchanged.
