Same way as anyone else (heart, lungs, brain, whatever else keeps me ticking)
Honestly, I've never been much of a gamer. I've spent a lot of time in my life doing other things that I've found more enjoyable (walking, hiking, camping, any family function ever, movies, other things I can't mention). Playing games has always been a casual enjoyment for me. I'm not gonna become a snivelling crybaby just because I don't have any consoles. I wouldn't mind getting a PS4 one day, but it's so loooow on my priority list, basically at the bottom. I've got my laptop to give me my occasional fix.
