Actually, some scientist claimed a while back that video games actually improved the reflexes on kids.
Personally, I find this to be VERY true. I started playing pc games (ive never been much into consoles) at 14. Before that you could be swinging a baseball bat at my face and I wouldnt dodge it... now today people are amazed at how quickly and how CORRECTLY i react to situations by reflex action.
Like the driving example. Many times ive been >< this close to getting hit head-on by some love muffin that cant keep his car on his own 2-way lane and ive avoided them by a slight, instantaneous move to the side.... without even getting excited, panicked or scared (but MIGHTY pissed off afterwards). I'd say that many people wouldve either jerked the car hard to a side (as ive seen my parents and "older generation" folks do) or just frozen.
And in other little things in life! How many of ye are strategy gamers? Any of ye realized you can easily find yourself organizing entire situations "in queue" and anticipating things you might need to do and mentally being ready for it? Ive cought myself so many times by having the solution to a group-problem whole minutes before anyone else.. AND knowing who to tell to do what , when and where to get the thing done. You chop wood, you mine gold, you get busy building that hut..we got any dragons yet?
