Old Video Games
I wonder how much of my life has been wasted sitting in front of a TV, playing video games that are over 10 years old. I tried to think of a skill I've developed, or some benefit to playing first generation Nintendo video games, and I can't think of anything beyond the weak argument that it improves hand/eye coordination. There's probably a saturation point or diminishing returns on putting time into Nintendo to improve your hand/eye coordination. I've settled on a "do it while you can" attitude when it comes to wasting time in front of an old TV with even older video game system. I'm through trying to rationalize, time to go for the gusto.
