see, no way for a man to be SURE a kid is his, so his best chance of passing on his genes is sex with lots of young, fertile gals. That "lizard brain" stuff has a lot to do with what you find to be attractive. It's also a status thing, to have lots of gals being your "partner." A woman needs help raising the kid, so she seeks to KEEP ONE guy, and since she is so limited, her status-seeking impulse leads her to seek out the BEST guy she can get/keep. So you young guys are blowing smoke, might as well just concentrate on learning something that women dig, like playing guitar, singing, dancing, or making big money at something. Better yet, get an Asian Lady. All she asks of you is that you GET her here, and she will do the rest. You have a 5 year "warranty" on her, because if she divorces you sooner than 5 years, or runs off, she's going to spend 6 months in jails/ICE holding pens, then get deported. They all know this, so they stand by you for 5 years, at least. You got a 5 year guarantee on any US woman? There's millions of loveley, smart Asians who will do nearly anything to get a US "green card, guys! Let these US gals KEEP that old thing.
