Proof that older = wiser:
Age at marriage for those who divorce in America:
Age Women Men
Under 20 years old 27.6% 11.7%
20 to 24 years old 36.6% 38.8%
25 to 29 years old 16.4% 22.3%
30 to 34 years old 8.5% 11.6%
35 to 39 years old 5.1% 6.5%
However, proof that we don’t learn from experience:
50% percent of first marriages, 67% of second and 74% of third marriages end in divorce.
