The duality of a developer's existence laid bare. Spend 8 hours hunched over a keyboard like a gargoyle with deteriorating posture, complaining about back pain and needing a standing desk requisition form... then somehow manage to sit perfectly still for a 12-hour gaming marathon without a single bathroom break. The human body is remarkably selective about what activities it considers "painful."
It's almost like our spines have a special agreement with Steam: "Oh, this isn't work? Carry on then!"
