Bones, stop growing after puberty and muscle and fat cells also stop dividing. But cartilage - that’s the plastic-like stuff in ears and noses - cartilage continues to grow until the day you die. Not only does cartilage grow, but the earlobes elongate from gravity. And that makes ears look even larger.
Older people do have larger noses and ears. What to do? Rhinoplasties can pare down that extra cartilage that gives you that bulbous nose. And your plastic surgeon can get creative and whittle down your earlobes so they fit nicely inside your earphones.
