It also takes your mind away from any tension or negative thoughts that you may have and helps beat stress.And if you have some serious talent, and if you can put more hours in playing, you may go pro and compete in national and international tournaments, earn huge amount of money and become a celebrity. If you cant become a pro, you may stream your game and have followers as well as a decent income.
If you are a student, you can take a career in Game Development, Game Programming, Game Testing, Game Designing and so on.
If you are already busy the entire day with some serious business, or have something more productive things to do, then too, playing for about an hour isn't a waste of time.
