Middle school grads' life quality best

Middle school graduates live healthier, happier lives and adapt better to society than those with either higher or lower educations, a recent survey showed.

The research randomly selected 12,000 questionnaires from a pool of 300,000 patients who had undergone routine health examinations at Daping Hospital from 2010 to 2014.

The hospital is affiliated with the Third Military Medical University in Chongqing.
