You mean Somali women don't age too well? That one I can agree on.
Somali men are known not to crack. My father is his 50's and he looks like he's in his 40's and I have seen tons of Somali men in their old age who look very young. Literally so many and it's because they have good genetics.
I could give you an example how Somali men have good genetics and don't age.

Farmaajo is 56 years old but he looks like he's in his early 40's.
