A school in San Francisco has introduced a course on how to fight using a lightsaber. Yes, the glowing sword which Luke Skywalker used to take on the evil Darth Vader in Star Wars. The hour-long class costs only Dhs60 and teaches you the right and wrong techniques to use when battling other intergalactic beings. You also learn how to be a Jedi and how to ‘use the force’. Beats a yoga class any day!
