Why shouldn&#x27;t women quit at age 50 because of children? If they sacrificed family time for their career before, they might realize that suddenly there is not a lot of time left with their children before they will leave the house. Maybe at 50 they have secured enough money as well to be comfortable working less. Older men seem to be taking time off for family, too.<p>It&#x27;s a shame that they have to discredit their paper by ending it with pure speculation (&quot;could include...&quot;).
