All I really meant by that comment is anybody who's that good spent a huge amount of their free time practicing and learning to play. But the definition of "giving up your childhood" can certainly vary. This is from the About page on Facebook.

Yohan was born and raised in Seoul. He has perfect pitch and can reproduce any melody on the piano after only hearing it once. While he started playing the piano very young, he only started uploading videos of his music to Youtube when he was ten years old

Perfect pitch is a great start but it does nothing as far as actually learning the piano, hand independence, velocity, touch, all that stuff. That takes years of practice just to learn the physical part of it.

On his YT site he mentions he started playing at age 3. I would assume that pretty much consumed his childhood but who knows? No mention of formal lessons though.
