Why don't you "gamers" try lowering the dopamine hit you get from sitting in a chair and allow your brain to get rewarded by tangible achievements? After a few weeks it will reset your reward system and working on physical projects and going outside will be fun again. Then all that time you're spending will actually create tangible things (muscles, real life skills, building things, etc) Instead of digital 1's and 0's that can't improve your life.
