I'd like to disagree with this, and actually vouch for the opposite.
From a biological perspective, yes, you can say women Peak and mature sexually at 35, while we men get fully ripe by about age 19. But you can't say it starts going downhill after 19...we probably plateau and remain horn dogs for 20-30 more years until the "tools" start rusting.
But when it comes to what really counts, our value or appeal to the opposite sex, the opposite is true. For guys, after age 19, our worth increases until the 30s/40s as we accumulate knowledge, experience, wealth, stability, etc. On the other hand, for girls, their value peaks at the tender ages of 18-28, and then it starts to depreciate...
The truth is there are not enough jobs in the Phils even if you have a degree and even if you get a job the pay would be less than a DH. A teacher in Phils will earn less than HKD 2,000 per month. No they don't hand them out, they have to work. Many of the degrees are of suspect quality I admit. You could say the same about UK degrees where 90% plus pass, I guess it's the same in USA and Oz.
And exactly who is to say what generates love for another person? Maybe I fall in love because someone has huge boobs, maybe I fall in love because someone has a nice smile, maybe I fall in love because someone is kind, maybe I fall in love because someone takes care of me well, maybe I fall in love because she is a demon in bed...Maybe because she challenges me intellectually or physically. Who cares frankly if it works...
Trying to judge other people's motivation, values or emotions by our own is extremely egocentric...
Case and point with one of my friend who married a very attractive, professional lady who is way richer and more successful than him and quite a bit younger. He is quite overweight, not the swiftest guy around but he has a heart of gold and she certainly seems to love him.
I would never in a million years have a relationship a DH, someone from a poor country, someone uneducated, a smoker or drinker and I've never really been interested in women way younger than me although I don't reject the idea out of hand. That's my decision according to my values and I don't see why I should look down my nose at people making different choices...We all fart out of the same orifice and we'll all end up the same way... Dust to dust! Just because you might not find happiness a certain way, it doesn't mean other people can't...
