I trained in the Bujinkan for over 10 years and I miss it. Other things have got in the way for the moment but I will get back eventually.
Anyway, I am reading 'Brain Cuttings' by Carl Zimmer. One if the chapters talks above how the workings of the brain form to speed up our slow down neurons in order to sync anything up. Some reactions can be pretty slow but at least they feel in context with experiences around them. For example, i find it odd to watch a jack hammer in the distance that is desynced with sound.
So our brains are built to sync audio and video. I wondered though if the likes of martial arts training helped an individual feel comfortable with processing mis-matched data for the various senses? Would this explain why the top grades seem to be able to do things that seem spooky to anyone who hasn't trained?
This idea might not hold water of course. One immediate problem that I can think of is that the nature of our senses are to signal change in the world rather than reporting the full current state.
Anyway, all worth a thought.
