The wall is as described

When a woman is 29-32 and single, she begins to prioritize finding a long-term partner for marriage and having children, this two things become her top priorities vs when she was 22-24 and didn't consider such things

From 21-24 those are labeled as her "fun/party" years and from 29-32+ those years are called her "epiphany" stage

Now misconceptions

"She can't physically attract any man once she hits 30"

This is a common lie among this sub, l don't know who got the idea women suddenly loose their beauty once they hit 30, a woman can still relatively attract men in her 30s because makeup exists and many other metrics she can use

Again the wall isn't that she looses her beauty but she now has to focus on finding a LT man and having children due to the biological clock many women are aware of
