I love their martial arts information section:
" Martial Arts
various forms of self-defense, usually weaponless, based on techniques developed in ancient China, India, and Tibet. In modern times they have come into wide use for self-protection, as competitive sports, and for exercise. Jujitsu teaches skills that enable one to overcome a bigger, stronger opponent. A popular style of jujitsu is aikido, which uses wrist, elbow, and shoulder twists and graceful falls; it is noncompetitive and incorporates various spiritual concepts. Other popular forms of martial arts include kung fu, karate, and tae kwon do, all of which emphasize blows with the feet and the side of the hand, and kendo, in which leather-covered bamboo "swords are used. All styles emphasize allowing ki (cosmic energy) to flow through one's body. This belief in ki connects aikido with t'ai chi ch'uan, a meditationlike discipline that emphasizes slow, graceful body movements. The most popular form of individual exercise in China, t'ai chi is often performed publicly in large groups; it has been claimed to reduce stress and lower blood pressure. Judo, a Japanese sport created in 1882, makes use of jujitsu principles. Capoeira, a dancelike Brazilian discipline, is gaining in popularity."
