I have not studied judo yet, but am looking strongly towards it right now. As some people have said, it is an art which you can practice at nearly full strength. How many other arts do so? There are some, but not all. I will not give credit to the notion of "95%" of fights going to the ground or whatever it is that circulates around. Bottom line though, is that if it gets close enough to grapple, throw and/or fight on the ground, I hope you know what you are doing. If not, you are likely going to learn a quick lesson. Anyway, I chose to respond to this because I am likely choosing judo and wanted to explain why. I feel it can be effective. Will I go into a bar and take on 3 guys? Lemme think about that.....ummm no. If a guy attacks, will I be able to do something? Depends of course. If he cheapshots me, or jumps from behind, the cards are already against me. It is just like any other art. Learn what you can, and more importantly, learn how to use it on the street if you ever intend to do so.
