Fighting in Class?!

I found this awesome video of unarmed combat being taught in gym class. An activity like this would be great for high school level students. Safety is always first, so I would definitely talk with my students first about proper technique and the only appropriate time to use this skill is in this class. I think this would really teach the boys (and girls) the definition of meek. Meek means power and strength, under control. This type of controlled combat would also relive a lot of aggression and perhaps help some students get through the day. Basketball and soccer are great sports to play, but it's nice to change it up over once in a while for kids to get a chance to experience the most they possibly can.
