Jet Ski is the brand name of personal watercraft (PWC) manufactured by Kawasaki Heavy Industries. The name, however, has become a genericized trademark for any type of personal watercraft. Jet Ski (or JetSki, often shortened to "Ski") can also refer to versions of PWCs with pivoting handlepoles known as "stand-ups." Sit Down PWCs are also called "Jet Skis." Also, "WaveRunners" and "Jet Skis" are essentially the same thing; but "WaveRunner" is the trademark name for Yamaha's line of water craft. Whereas "Jet Ski" is the trademark for Kawasaki's line.

Any jet ski worth driving will have a safety key. This is usually a bracelet tethered to a little plastic clip that attaches itself to a spot on the handle bars. This key needs to be engaged on the jet ski's handle bars in order for the engine to start and run. The tether should always be around your wrist; if you fall off of the jet ski and you are not wearing the tether, the jet ski will keep going. If you are wearing the tether, the plastic key will be pulled out and the engine will stop. This can be handy when it's time to swim back to the jet ski.

To right your jet ski, swim to the rear and flip the boat over in the direction indicated on the back of the jet ski. Every jet ski has a specific direction that it is easy to flip it back over and a direction that it is impossible. If you can't make it flip back over, try flipping the other way. It should be easy to right the jet ski.

Karate is a martial art developed in the Ryukyu Islands (Okinawa) from indigenous fighting methods te and Chinese kenpō. Karate is characterised as a striking art using punching, kicking, knee and elbow strikes and open-handed techniques such as knife-hands (karate chop). Grappling, locks, restraints, throws, and vital point strikes are taught in some styles. Karate developed in the Ryukyu Kingdom prior to its 19th century annexation by Japan. It was brought to the Japanese mainland in the early 20th century during a time of cultural exchanges between the Japanese and the Ryukyuans. In 1922 the Japanese Ministry of Education invited Gichin Funakoshi to Tokyo to give a karate demonstration. Keio University became the first Japanese university to open a dojo; by 1932, all Japanese universities had dojo. In this era, the name karate was changed to karate to indicate that the Japanese wished to develop the combat form in Japanese style. After the second world war, Okinawa became an important United States military site and karate became popular among servicemen stationed there.

The martial arts movies of the 1960s and 1970s served to greatly increase its popularity, and the word karate began to be used in a generic way to refer to all striking-based Oriental martial arts. Karate schools began appearing across the world, catering to those with casual interest as well as those seeking a deeper study of the art. Shigeru Egami, Chief Instructor of Shotokan Dojo, opined "that the majority of followers of karate in overseas countries pursue karate only for its fighting techniques depict karate as a mysterious way of fighting capable of causing death or injury with a single blow...the mass media present a pseudo art far from the real thing."Shoshin Nagamine said "Karate may be considered as the conflict within oneself or as a life-long marathon which can be won only through self-discipline, hard training and one's own creative efforts."

For many practitioners, karate is a deeply philosophical practice. Karate-do teaches ethical principles and can have spiritual significance to its adherents. Gichin Funakoshi ("Father of Modern Karate") titled his autobiography Karate-Do: My Way of Life in recognition of the transforming nature of karate study. Today karate is practiced for self-perfection, for cultural reasons, for self-defense and as a sport. In 2005, in the 117th IOC (International Olympic Committee) voting, karate did not receive the necessary two thirds majority vote to become an Olympic sport. Web Japan (sponsored by the Japanese Ministry of Foreign Affairs) claims there are 23 million karate practitioners worldwide. A karate practitioner is called a karateka.
