well yeah. You see it in cycles from a personal POV, or in groups from a displaced. The relationship/divorce treadmill, watching your old friends go on and off the market over decades. the 30 year olds are either in committed relationships with kids or not whatsoever. the 40 year olds of either type are on the dating apps, fresh divorced and back on the market or never married wondering why the supply has gotten shy. I did notice a spike around @28 when the early achievers finished their first divorce.
