The age gaps spanned anywhere from 10 to 14 years, with women in their late 40s and early 50s enjoying relationships and/or marriage with men in their late 20s or 30s. Couples in this situation had to address the fertility concern head-on, with some choosing to take the leap relatively quickly while others took a pass.
Culturally, the older woman/younger man dynamic is perceived as an oddity, or a fluke.
In fact (and very heteronormatively speaking) older men dating and marrying younger women is so much the norm academia still hasn't gotten around to more intensively investigating the older woman-younger man dating dynamic.
One of the only studies I could find on the topic, "Older Women/Younger Men: A Look at the Implications of Age Difference in Marriage" notes in its abstract (ah, the frustrations of journal paywalls): "While there is a lot of information in the literature about men who date and marry younger women, the research on this subject is very limited or outdated." What the researchers did find in their interviews with eight married couples with wives at least 10 years older than their husbands echoed part of the You Tube commentor's query: the men especially enjoyed the women's maturity and confidence, while the women appreciated the younger guys' vitality.
But let's be fair: There's a reason we tend to date people who are closer in age.
So, if something seems too good to be true (read: he or she is too hot for you by about eight years), it probably is.
