Capoeira - Cool Martial Arts

I've noticed I post many of Sabrina's activities. My son, Brandon, has many interests as well. He "loves" Capoeira and is currently enrolled in Kikara Kickboxing. He'd like to switch, but I'd much rather keep him in something safer, where they only learn to break opponents arms and legs and such, and not their necks. Capoeira seems to be more like martial-gymnastics-art, sort of like kickboxing, but with style.
