Tiny ears - teenager. Huge ears - senior.
> This study supports the view that as people age, their ears get larger, particularly the ear circumference, which increases on average 0.51 mm per year. This enlargement is likely associated with aging changes of collagen
So they do get larger with age but not due to growing, but rather the typical aging of the skin + gravity tends to result in the ears enlarging in diameter.

Can you tie them in a bow?
Can you throw them over your shoulder like a continental soldier?
Do your ears hang low?
