Okay, now that my basic feeling regarding that bit of claptrap is dispensed with...
It is true enough that pheromones change during cycles of fertility, when no longer ovulating women put off fewer / different kinds of these pheromones.
HOWEVER, studies suggest that using birth control affects this "attractiveness" feature in many ways, not only through the perceptions of the prospective partner, but also for the woman herself (causing her to choose men more "brother" than "baby-daddy")...
For health reasons, women generally are encouraged to stop using birth control in their mid-30s. So, given these (admittedly circumstantial) clues, one could be led to conclude that women are MORE attractive at 35+ at a basic biology level, than they are prior to that time of their lives.
(Yup, married my then-24yo hubby when I was 37. I am living proof that my theory holds some truth. )
Source for that 'mothers are less depressed than career women'? While I know a few somewhat sad middle-aged women who never married, I also know some really cool women who never married but got the most out of life instead, and some married women who are miserable. Personally, I quite like my husband, but I know I'm missing out on some fun stuff.
Men can balance fatherhood with career because there's often a woman around to do the hard work of parenthood. That's a strong recommendation against motherhood, in my opinion, unless you're damn sure your source of y-chromosomes is going to change the nappies.
You'll find on this forum there are a lot of self appointed experts on every subject, very few of which have actual sources of their facts, but also believe if they are aggressive enough in their responses, it's about the same as true facts.
From age of sexual activity until roughly 35yrs, women "tend" to be on the pill, affecting the type / level of pheromones they put out, which in turn affects their "attractiveness" to the opposite sex.
Taking the pill beyond age 35 increases the risks of getting cancer, so more and more, doctors are recommending that women come off the pill by then, and use alternative (aka "old fashioned") methods. Lack of pill - while still fertile - means pheromone levels go back to something like normal, increasing their "attractiveness".
Well, since there's some stereotyping going on, I'll lay it on thick too (turnabout being fair play, eh?):
We do need to keep in mind that not all of the members of the forum hail from the same backgrounds. Some may come from areas of the world with more "traditional" gender roles - and may be more stuck in their minds about keeping the roles that way.
I'm still trying to work out what the OP's motivation was for his opening post..
Simply, and unfortunately, the dating scene is a market place, and the balance of supply and demand and the way this is negotiated depending upon the cultural, professional and educational landscape. Zürich and Sydney have a similar landscape in this regard, so this SMH article could be applied here. Similar polarisation in a superficial town such as ZRH or SYD such as in this article are also relevant.
I can only say my experience is similar to that of those in the later part of the article. I struggled to get attention/dates in my 20s, but in the last 5 years I've been courted/chased/stalked like never before...although I choose not to exploit many opportunities because I don't feel it fair to waste the time of others. Other men are perhaps not so kind.
Having said that, the beauty about humanity is there will always be deviance and exceptions from what is supposedly accepted or expected...so none of this applies if you are prepared to live your life outside the box.
Seriously, that's the most ignorant stereotyping I have read on here for quite some time. Even for EF standards. And you are not just insulting most females on here (either being careerist or on the other hand some opportunistic foreigner looking for a rich guy...), but also all the men in international marriages cause they were too backward and weak to deal with modern western women...
May I ask if you have ever met any Asians, Russians and so on or do you get that insight from Blick?
Trouble is, if you tell young women from the start of their life that they're more domestic, less aggressive, and going to do less high-ranking jobs and earn less than men, it's a self-fulfilling prophecy. This destroys the potential of some women to be anything else.
Sure, there are worse problems in the world, but let's start from the premise that 'people having children later' isn't just A Problem For the Women, or worse, A Problem With the Women. If the OP is worried about the implications for the human race, I suggest s/he either a) start working towards a uterine replicator or b) become a nanny, depending on skill set.
I like to compare women in their late thirties who are picky to Koala bears only eating a particular type of eucalyptus tree in a dwindling forest.
Don't shoot the messenger! While I don't think people should be with someone because they think they can't find someone better, there are certainly market dynamics at play which makes the dating market for women in that age more difficult.
The only thing that could level the playing field somewhat is when the majority of women would accept dating younger, less educated and less succesful men. Biology would still dictate a lot of the market dynamics but that would change things quite a bit.
