People's self-esteem reaches a peak at 60 with the highest levels being enjoyed by well-off married men. Ulrich Orth from the University of Basel studied 3,617 American men and women aged between 25 and 104 between 1986 and 2002. The study found that self-esteem peaked at 60 but declined thereafter due to retirement and failing health. Better education, income, health and employment status were all linked to higher self-esteem as was being in a happy marriage. Apart from people in their 80s and 90s women tended to have lower self-esteem than men.
