I won't speak for other black foids, but the issue with black foids from the US is that they tend to start at a disadvantage facially as is. They would have an advantage over white foids in aging but they ruin it by doing the same destructive (if not more) habits of white foids. Becoming fat, doing outrageous acts with their hair, coping attitudes, stretch marks from childbirth, etc. Stats tell us over 70% of US black foids are obese.
Black women famously avoid exercise for spurious and idiotic reasons (when is the last time you saw a black foid jogging or at the gym?) and somehow believe weaves in their hair or painted fingernails is adequate compensation. They never face the consequences of this behavior though because there is no sexual selection pressure on females, and black women are no exception to this rule. They still get hoodrats and even tyrone to knock them up so one can hardly hold them accountable.
