What? I don't find that at all.
People are too stressed and exhausted to live at a basic level, that tends to impact their ability to game although sometimes it makes them even more competitive with the small amount of time they have... but no I don't agree at all.
I am far better at video games than I used to be, admittedly I play a lot of them but that only makes my hand eye coordination locked in, the actually "being good" at games has little to do with that most of the time.
