(LOGIC TEST!! He has trained so much he does it wouldve thinking he just knows when theres a way to easily kill someone before even knowing the way he just does it without even a millesecond thought)
(Science: While you are not concious of it, your brain has to think in order to process the messages the senses are sending it constantly)
(but even so that less than a millisecond would notify me and I would be able to move my leg in time)
(not really if you move your leg it technically isnt a thought it sends a message to the sub concious part which isnt the thinking part)
(I also have trained *cough* over 2 previous lifetimes *cough* and I also have reflexes that rely on those less than a millisecond thoughts)
(its impossible try to see how a crack moves it moves less than a millesecond and you cant see it happen)
