Upward Mobility Can Be Hazardous to Your Health

A study of hundreds of low-income American youths shows that at age 19, those who had been rated as diligent and academically successful were less healthy than peers who had been labeled aggressive, difficult, and isolated, a team led by Gregory E. Miller of Northwestern University writes in The New York Times. Highly motivated people from low-income backgrounds often feel tremendous internal pressure to succeed, but behaving diligently all the time may leave them feeling exhausted and sapped of willpower, and they may let their health fall by the wayside, the researchers say.
