"You find this drop in happiness in women regardless of whether they have kids,
how many kids they have, how much money they make, how healthy they are, what
job they hold, whether they are married, single or divorced, how old they are,
or what race they are. (The one and only exception: African-American women are
now slightly happier than they were back in 1972, although they remain less
happy than African American men.)"
