Hi, apparently if you were to mark the inside of your ear with indelible ink over the space of a few months the dot would move out of the ear......due to the skin of the ear always regenerating and growing....don't ask me how I know this.....lol
its true that your ears can still grow after you have 'matured' ohysically as there is cartillage around them.your nose too(as i can bloody testify!).some people get a condition where their ears, nose and short bones(on hands and feet) keep growing in adulthood.techically its only your long bones(arms and legs etc) that have no possibility of growing any more once you reach maturity.
