Re: Aikido does not work at all in a fight.
Oh, to add a serious comment. You don't go to the ground cause you want to, you go there because that is where you end up. It is but one aspect of fighting, the one where you fail. The point is when someone closes distance and attacks and is jacking your OODA loop all up, things like falling down tend to happen.
Having the skills to recover from this are important. Getting to your feet is very important. Guys that train in grappling systems...contrary to aiki-land belief can actually discern reality from sport in applying their KSAs.
