Sh.t, you got me Jay.

The martial arts in China and Japan were all conquered the moment the gunpowder was invented in 18??

So, yes, after that you could be shot by the first fool with a gun, despite the fact that you have trained all your life.
Even being capable doing the most bizar and impossible seeming things, you cannot deflect a bullet.

Note: the ultimate state of a martial-art fighter is "Shen", which means having willpower, literally.
So maybe with "Shen" one can stop a gunman to shoot or even let the gun fly out of his hand.

Or better, one feels and predicts the whole confrontation and doesn't leave house that day.....

By the way: my chinese martial art master once let me feel his willpower, standing 20 m. distance of me !
He just stared at me and I felt suddenly a punch in my stomach so hard that I knocked double screaming from pain.

No one believes this story, but I know its true.
