Alright, after reviewing the Ninja problem, my training in Taekwondo comes to mind.
I started when I was eleven, (I'm 20 now, btw.) And now I'm a third-degree black belt, nearing testing for the Fourth degree, now, as I've been in Taekwondo for so long, I've seen a whole lot of people.
-Particularly, children. There's even a program called Tiny Tigers for them, for the kids too young for the regular class, and I've seen those kids get older and become flat out amazing
Basically it's a roundabout way of saying that if they had been trained from anywhere below age of 6 , at 16 they would be a master of it, but no Secret arts bullshit, the Legit parts of Ninjutsu.
hey, you learn taekwondo as well? i started a few months ago and im a green belt (i know, i know, will train harder).
Well, there's a helluva lot of different kinds of Martial Arts, however, I'm in the largest in the world, the ATA, or American Taekwondo Association.
wow. compared to that, the group lessons i get are like nothing.
