“The Wall” from what I can see, is loosely defined as the following for the end of women’s peak dating/mating attractiveness, dictated by the response from men by men’s biological mating drives/nature:

  1. An apples for apples comparison: A 22 year old woman is more attractive than that same woman when she eventuall turnes 30 or 35 or 40 years old.

  2. A time in a woman’s life where a womans fertility/eggs are running out OR

  3. A woman’s eggs are severely compromised in quality to a point where the chances of healthy conception with a healthy child with no medical issues becomes significantly LESS likely

  4. A woman’s youthful looks “wearing out”, presence of wrinkles or deterioated body composition to a point where she no longer appears “youthful”, generally noted by her tired skin, hair thinning & looking less healthy, hair doesn’t grow to long lengths anymore, start getting harder & very soft rather than “firm but yielding” of youth.

  5. When a woman has a significant decrease in the amount/quality of men actually wanting to commit to her (long term or for marriage & children).

They may still have men approaching (certainly less in number/quality than when they were youthful) but quantity will have decreased significantly, the quality of those men will have dropped significantly also.

  1. Going further when women are much older: becoming what women have termed “invisible” to most, if not all society (outside your immediate family & friends). This generally happens to women who become very unattractive and/or those over 50 years old (+-5 years).

  2. A woman’s (youthful/attractive) physical appearance no longer able to help her out in other areas of life or people (of both genders) suddenly becoming far less nice, less accomodating and less likely to receive any benefits or additional priveleges as received by their younger selves or in comparison to youthful women currently.

  3. The best man (for commitment/marriage) that a woman can EVER get is firmly in her past and that opportunity to get commitment from a man of that quality has zero possibility of ever happening again.

Now alot of the above may be seen by very attractive women that started that way and continued to be so in older age - but that eventually runs out at a certain age.

Note: there is always exceptions like Sofia Vergara but those exceptions are so rare and in unreasonably low amounts in real life that it’s not worth discussing. A point can’t be proven by exceptions but by the majority.
