I never said that the average BW was nicole murphy. I said that on average, apples to apples, BW age far better than WW, and that is truth.
Why Do We Age Differently?
BW have thicker skin, and melanin, and don't be out in the sun as much as WW--which contributes to less wrinkles, us maintaining more collagen in our skin, and less sunburn/sun damage. WW have thinner skin, obviously don't have the melanin we do, and obviously be out in the sun way more, which are the main causes of them aging the way they do.
Putting that aside, you've said before that you live in a state where there are a lot of overweight women. I think that may be why you believe that all women age terribly. I've lived in many places, and yes, in my experience(and according to research) there is a usually a drastic different between races when it comes to aging.
Of course a woman that is 35 won't look the way she did at 25. That was never my point. My point was apples to apples, if you compare a group of late thirties/early forties WW to a group of late thirties/early forties BW that all live similar lifestyles, the BW will take the lead in aging far better. That isn't to say that all bw age nicely(because I never stated that we all do) but we are more likely to age better than WW, and that cannot be denied.
As for as weight goes, yes BW are more likely to be overweight and fat, when compared to WW. I don't know what your comment about hair means though.
