Have you been to Asia?
Yes? Came back from another visit to thailand just yesterday. Been to the flips too. What about it?
There just is no continuous aging process when it comes to Asian women (at least the good looking ones). They eventually flip to "old" mode once they turn I don't know, 80 or something.
When a female friend of mine who is half Swede and half Thai celebrated here 30 birthday here mom and dad was there too. The birthday girl looked 30 her dad, who is Swedish, also looked his age, but her mom looked like 25, I was amazed. And I have later noticed that some Asians seem to age very slowly up until quite a high age, at witch time they seem to age very rapidly and catches up with us Europeans.
I don't think that this has to do with nationality, but more about the specific family genes. If there are many generations who are healthy and active, then their offspring will be more favored to these traits.
