:Physical Activity and Sports:
Many (perhaps even most) hackers don't follow or do sports at all and
are determinedly anti-physical. Among those who do, interest in
spectator sports is low to non-existent; sports are something one
*does*, not something one watches on TV.
Further, hackers avoid most team sports like the plague (volleyball is a
notable exception, perhaps because it's non-contact and relatively
friendly). Hacker sports are almost always primarily self-competitive
ones involving concentration, stamina, and micromotor skills: martial
arts, bicycling, auto racing, kite flying, hiking, rock climbing,
aviation, target-shooting, sailing, caving, juggling, skiing, skating
(ice and roller). Hackers' delight in techno-toys also tends to draw
them towards hobbies with nifty complicated equipment that they can
tinker with.
