I used to be snacking all the time, I was an eating machine. But one thing I never did was snack when I was playing video games. I was too immersed in the game itself and I wanted to keep my fingers clean too, so that I wouldn’t have to clean my keyboard!
But if I were to play something like Nintendo’s Wii with friends then a bowl of chips or similar would all be part of the ritual and fun.
Of course, my gaming sessions don’t last for many hours or into the witching hour, but I suppose you young’uns need all the sugar you can get!
One thing I do always have on my desk is a bottle of water though, certainly couldn’t live without that when playing.
