I've heard it clears up again after the first wave of divorces

Am I the only one having a stroke trying to understand:
"clears up again after the first wave of divorces (after 35?)"
Seems plausible. Most of my friends got married or "like-married" between arround 28 and 32, then the divorces happened between arround 35 and 38. Those who survived that wave are still married.
