Everyone under 30 is prematurely old (worries and stress about savings, career, future, ...)
Everyone over 50 is desperately young (Burning Man, psychedelics, trendy clothes, style, image, adapted to modern social media terrorism by 'coolness factor' and being part of 'community', ...)
Theory: Information abundance
-
aged the young by showing them all future problems all at once.
-
also made the old young by showing them all missed experiences all at once.
So now "Gen Z talks like retirement planners and boomers act like teenagers."
Also don't forget all those debts - will surely evaporate as soon as the generations die.
Even more importantly the responsibility of adults for the youth and the world.
And don't forget all those old women in their daughter's ass push-up leggings!
"It's so over."

Best comments reward:
"Do you use face cream made from foreskin?"
"this is 59." - "This is adrenochrome!"

"Women over 30 should not be allowed in bikinis"

Or maybe the theory is "54 years of fiat debasement and government overspending, esp after COVID."
"The young have to grind more than ever while the old have had decades compounding in wealth assets and have FO money to do whatever they want."
