The Daily Mail reports:
Workers lose their ambition at the age of 35, a study has found.
Researchers in the U.S. found that ambition at work had declined overall in the past 15 years - especially among men.
The age of 35 is the age when men and women no longer compete with their colleagues for promotion or seek greater responsibility in their roles.
... As reported by The Times, in 1992, 59 per cent of men of all ages said they wanted more power and responsibility in their jobs. But by 2008, this was figure was down to just 44 per cent.
