Some martial arts Id suggest are Taekwondo, the Kungfu styles of the Tiger,Northern Shoulin, and N Mantis, and the Japanese arts of Kempo, Karate, and Kendo(Japanese swordsmanship) because the use of the sword never dies. Even a million years from now swordsmanship will continue as long as there is such thing as original sin. I also suggest fencing. If you practice real hard you will in time be able to side kick an attacker from a distance of 15feet in less than 2 seconds. My Taekwondo Master sure can! He could kill you with a pencil with a broken lead!
