Age gap relationships aren't more likely to end in divorce, as per the largest study ever conducted on this topic - whole population, millions of people, spanning more than four decades. Tiny studies that claim "+1 year age gap = +1000% risk of divorce!!" are not reliable.
99% of "fitness" influencers, actors, etc. being roided to the gills (and lying about it) exacerbates hypergamy by inflating female expectations. Women at most fertile years naturally prefer "ottermode" look of youth, on average, but women are also obsessed with male "status"...
So, if dating a bulbous juiced up freakazoid becomes universally "high status" among women, it could produce the same memetic Fisherian runaway that led to the Height Problem (spawned entirely by intra-female memetics). The same criticisms apply to looksmaxxing.
Aside from abolishing women's rights, the only thing that would strengthen men's collective bargaining power is if we became universally fat and repulsive, which is the strategy women have used for the last few decades -- not that I would ever advise such a thing.
God I hate that graph. Do you know why it starts at 1550 and not earlier? Do you know why English people delayed marriage during the Late Medieval? Do you know *which* English people delayed marriage? Do you know why age at 1st marriage decreased during the Industrial Revolution?
Posting that graph in this context is even more ridiculous when the accompanying figure shows that 20-40% of people had shotgun weddings, meaning they were in clandestine marriages for who knows how long before they were forced by nature to make it official.
"Brains don't fully mature until age 25!" is pseudoscience weaponized by feminists to justify bad behavior. It has been refuted by mainstream academics, libtard mainstream media, and it even has a Wikipedia refutation.
The concept of a "fully mature" brain is also pseudoscience. This is a complex topic so I will attempt to simplify... Brain "maturation" = neural pathways becoming stabilized, large reduction in passive neuroplasticity (automatic rewiring), pruning of weak/unused pathways, etc.
Different brain regions "mature" at different ages, with some individual variability, e.g.:
Brainstem/hindbrain = infancy
Sensory & motor cortex = childhood
Limbic system = adolescence
Prefrontal cortex = early to mid 20s
Social cognition network = early 30s
Hippocampus = never.
