Hundreds of years ago the ancient monks of the Shaolin Temple realized, that a normal optical reflex was not enough to stop serious incoming attacks at full speed.
It simply takes to long, think how much time it costs to identify an attack on a visual basis, the signal has to be sent by the brain to the limbs for you to react and that simply takes too much time.
Recent studies show it's impossible for a person to block punches or to stop an attack at full speed based just purely on a visual basis.
It's the same reason a goalkeeper cannot stop a penalty in a soccer match unless he jumps beforehand in the right corner, it's just to fast.
The Shaolin monks therefore developed a special reflex training program called Chi Sao freely translated as sticking hands.
This specialized reflex training program that let's you react in a much faster way and is the only way to stop incoming attacks for the full hundred percent each and every time. Your opponent will be stunned asking himself just why he is not able to land a single telling blow and believe me I have seen and felt it in action.
