@syz I am under the impression that is a myth.
You may be right, though, the internet seems to be torn over it.
ETA:
I just found this:
“Around age 18, ears and noses stop growing and there is no new cellular development, says Joseph O’Brien, M.D., orthopedic surgeon at George Washington University Hospital in Washington.
That doesn’t mean the size of people’s ears and noses doesn’t continue to increase as they age, O’Brien says. These facial features increase in length because the cartilage and skin lose elasticity, causing them to appear droopy. And gravity pulls those loose fibers downward, adding to the saggy appearance, says Robert Kotler, M.D., a cosmetic surgeon in Beverly Hills, Calif.”
…which might explain why the internet can’t seem to agree on whether or not they actually do grow/get larger.
