Do your ears grow as you get older? 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.
What organs can regenerate themselves? The liver is the only human internal organ capable of natural regeneration of lost tissue; as little as 25% of a liver can regenerate into a whole liver. Regeneration is very rapid. The liver will return to a normal size in one to two weeks following the removal of greater than 50% of the liver by mass.
