While studying martial arts is no walk in the park, it's not rocket science either. Most people of average intelligence and physical coordinative skills, with sufficient dedication and training, can become reasonably competent fighters in shorter time than most people imagine.

Anyway, I was taking a morning jog here in jolly ol' China and found this dude practising his Tai Chi on the footpath. Took some happy snaps. I didn't know which exact form he was doing, but I recognised his movements as Chen style Tai Chi. I can't speak Chinese to save my life, but after taking the photos I said to him, "Chen Tai Chi?" And he nodded and said "Chen Tai Chi." I then took out my notepad and wrote down down some Kanji and he wrote down the address of a martial arts supply store which I hope to check out later.
