Maybe you don't see this dynamic, but it is far from uncommon. I ran across this statistic a while back researching another story. "Analysis of collated data from the US Census Bureau proves to be revelatory. Out of 100 U.S. marriages, 12 involve an older woman and a younger man. It would suffice to say that more than 1 in 10 marriages in America is that of an older woman and a younger man."
