Neijia (Pa-kua Chang, Fa-shu Tao, some Hsing-I Chuan), and Chi-kung (Wu Qin Xi, Yiquan, Tai-chi Ruler, & Ling Kong Jing). Iron palm training. Martial arts weaponry (Biao darts, shuriken, yawara, cane, Red sand, and Gurkha khukuri). Also my first love, the Wrist Rocket. That's about all the active stuff that might qualify as 'sport'. For hobbies, mostly I just collect DVDs and videotapes. Maybe cooking could be considered a hobby? Or internet exploring?
Think I saw him long ago on that TV show (https://www.imdb.com/title/tt0083473/), along with some guy that was equally good with a bow and arrows.
