Sleep time was minimal while work time was maximal in the age group 45-54 years, and sleep time increased both with lower and higher age.(1)The weird thing is that if you watch a lot of TV you get more eye-shut time:
Except for time spent watching TV, which increased with longer sleep times, all waking activities decreased with increasing sleep time.(2)Come to think of it, it's not that weird. Your eyes get tired, your eyesight deteriorates, you become a couch potato, need I continue? It's the same thing with gamers. The difference between gamers and TV viewers is the amount of adrenaline - Usually (and you didn't hear this from me) epinephrine (another geeky name for adrenaline) is more or less a deluge to persons that play action games, or games on which they get addicted. It's not bad, but too much is bad.
Keep your gaming skills sharp, your window to the world open (*hint hint* television), but don't stand/sit in front of a computer or a TV all day long!
