I met a guy last weekend who talked a lot about martial arts. Wouldn't drop the topic. It started to weird me out a bit, but I smiled through it. He said that martial arts trains you to get in tune with your senses. During training, he'd close his eyes and hold his arm against his partner, and then the guy would ask him which leg he moved, and he'd know -- based on his senses. He argued that when you meet someone, you get an impression and know if you like them -- this is based on senses, we've just been trained to repress them. His martial arts was helping him tune them back in. The entire time I sat there nodding and thinking, "Man, what are you getting from me right now, because I think you're insane." Perhaps in time, his martial arts skills will tell him these things.
