Instructors Sensei Joel Wheelus, left, and Sensei Michael Stabile demonstrate one way senior citizens can protect themselves. Aikido School of Self-Defense at 3281 Salem Road in the Salem Square shopping center, under the direction of Chief Instructor Stabile, is now offering free Saturday self-defense classes to senior citizens. Stabile said recent reports of muggings in Gwinnett County spurred him to action. "With what's going on with the seniors, we felt we had to do something," he said. "Anybody can do what we teach them here. We're offering the classes free and they can come as many times as they want." Aikido is a combination of judo, karate, jujitsu, bo-jutsu, yawara, aiki-jujitsu and a few other lesser known styles of combat self-defense. Stabile, who has appeared on cable news and authored a book on self-defense titled, "Escape with Your Life," also works as a consultant in martial arts. Regular classes for adults and children are offered seven days a week. For more information, call 770-602-2811.
