High kicks are very un practical for me now. When I was younger and practicing nearly all the time they could work, I was super flexible and fast and kicking someone in the head was very practical for me. not so now. I dont spend that much time on martial arts. I need practical techniques for my body right now. Low kicks to the shin leg and groin are practical, even the stomach at times. This is practical for most people. A martial art that doesn't require all your time to be able to defend yourself. you need something, simple and effective.
