Weird Fact: Your eyeballs DO grow.
It’s a popular myth that the human eye is the only part of the body that remains the same size from birth until death.
In fact, while babies’ eyes are disproportionately bigger than the rest of their features (helping fuel our definition of “cute” and “innocent” looks) they do still grow… from 18mm to 19.5mm during infancy, and up to 25mm by the time you’re an adult.
So while the human eye is slow to get bigger, it does increase in size by about 7mm (almost 40%) during the course of your lifetime.
Meanwhile, a lot of people think that your nose and ears never stop growing… but this is also an illusion.
Your nose and ears actually stop growing when you are 18 years old. They only appear to get bigger once you hit old age, due to the force of gravity pulling down on your skin.
When you’re young, you have plenty of collagen and elastin in your skin which gives it strength and suppleness. But that breaks down with old age, causing skin to lose its elasticity, and your nose and ears appear all big and droopy. They do not continue to grow in old age.
