I need a martial art that would be particularly useful for a blind man. My character would have learned this MA while sighted, and then, after being blinded, realizes how useful the martial art could be to him, or perhaps some subset of the art, and goes back and brushes up on it.
Thanks for any suggestions.
ETA (I don't actually know what ETA stands for, but it seems to be used this way.) Thanks everyone for the excellent suggestions! It's easy to discern "trends" in what you all responded with. I have a good idea how to proceed now.
