Yea I don't think the response above you actually understood my comment. I do play chess somewhat seriously and it's similar mental labor as programming. And I can only do so much more serious mental work after a day at work coding. And I definitely could not commit to two hours of serious chess study every day. Maybe 30-60 minutes of games & puzzles. Playing a sport is completely different from playing chess, the physicality of a sport is at least different type of challenge.
