If you're interested in self-defense, kendo isn't the martial art for you.

Regarding self-defense, martial arts aren't much of a shortcut. There aren't any supersecret moves you can learn in a day. You're just gradually going to learn how to fight better. Having said that, judo worked for me as a kid.

Anyways, if the guy's twice your size, you're probably screwed. Best defense is to avoid the situation.
