It's called a woman 'hitting the wall'.
FYI, ladies, your academic and career achievements are irrelevant. Nice to have, but optional.
All that matters is:
Are you attractive?
Are you fertile? (For those men who want to make babies).
Are you mentally well? Red flags: numerous conspicious tattoos, keeps too many cats, addicted to parties and boozing, goes to therapy and maybe prescribed with siaolang pills, subscribes to certain viewpoints on politics and the world, have certain cringe hobbies etc.
Are you a spendthrift? Spending most of your disposable income on stupid shit?
Do you have your shit together? Not necessarily about your career, more like being responsible for everyday life, does self-care.
