Unfortunately I wasn't lucky enough to get any of the good physical features that majority of blacks have.
Also depends on how much stress that person been though in there life, I remember back on AHH someone made a thread comparing rappers in their early 20s to rappers back in the day in the early 20s.
Pac looked older than he was in a photo of him in the Above the Rim movie where's Wiz kaifia or w/e his name his still looked like a teenager at the same age.
I'm pretty sure Pac having a mother as a drug addict and being dirt poor was stressful on that dude causing him to age faster and look older than someone like Wiz or Soljia boy at the same age.
There was some other rappers in that thread from back in the day but I forgot who they was lol.
Nas's life doesn't seem that bad so that probably helped him retain his good looks, he probably puts lotion on his face too. Or he has some great genes.
He also seems like a easy going, chill type of dude so that helps too
Yea growing up in QB during the crack epidemic probably was rough, but Nas had Jungle to protect him so he had nothing to worry about
