Why do people love Tae Kwon Do?

Karate and Taekwondo are still popular today for the same reasons that other sports are still popular today. They are a lot of fun.

Like gymnastics and fencins, karate and taekwondo were originally developed as a way for soldiers to fight on the battlefield. Rifles and tanks have rendered most such skills almost obsolete (but not entirely). Soldiers still use Martial Arts as away to train their bodies to be prepared for hand to hand combat.

As a sport, karate and taekwondo are impressive to watch.
