When I was like eight years old I overheard my mother and aunt talking about how apparently if you don't learn to wiggle your ears as a kid, you'll never be able to, and that they wished they could wiggle their ears
And little 8-year-old me went "oh man, I better learn to wiggle my ears now so I don't regret it later!"
Anyway I can now and I have never once gone "boy, good thing I can wiggle my ears"
