Living here in Seattle, my plan is just to not have an earthquake. I know we're due a big one up here, and I also know that they suggest having an emergency kit with water, food, flashlight and other essentials in case there is one. But, my plan is to just not have an earthquake. Of course, if there is a bad earthquake, I'm screwed because my plan really isn't a plan. The injury thing is ridiculous. I wish you'd just let that go. There's nothing to suggest that Stephen Hayes has a hidden disability in that video. Regarding training to avoid the ground, that's been addressed several times and summarized by many different posters. The gist of it is that it can work very well, provided that the system was developed outside of a vacuum, at least in consultation with competent grapplers, and instructed by people who know what they're doing. Going back to the Hayes video and others, the issue isn't that people are training specifically to counter BJJ or other ground fighting styles. Nor is there any problem with the idea that "the ground" isn't a good place to be in a fight. The disconnect is whether or not anti-grappling is a form of grappling. Most people believe that it is grappling, and so to be an effective anti-grappler, you really need some fundamental skills as a grappler. Avoiding the takedown, improving your position on the ground so that you can regain your feet, and protecting yourself while on the ground are all grappling skills. So, if you are a kung fu guy and just invent your own style, you're likely to come up with techniques like the Hayes sweep to a leg lock, that look good on paper, but won't actually work. That's it. The grappling contingent here has shown some examples of wing chun guys who do seem to be teaching competent anti-grappling. The difference being that they actually consult with grapplers, and so their anti-grappling looks fundamentally different.
