I’m 34, love gaming, and have been married for 12 years with 3 kids. “Healthy” amount of play is playing as much as you want as long as your on track in accomplishing your short and long term goals.
In addition, you need to make sure your wife’s expectations are being met daily. My wife lets me spend my time however I want as long as I’m clearly communicating my efforts in meeting her expectations, both in the short and long term.
