That nitpick is a bit like when people say BMI is invalid as an indicator for overweightness because bodybuilders are also categorized as obese by BMI. Except the confusion is impossible in case of a regular person. Similarly, there can be good reasons for being 12 hours on screens, but it will be obvious and exceptional. Yes an 18 year old may be a successful entrepreneur, video maker podcast host influencer who is reading ebooks for research or sending out emails or editing videos or programming a website in those hours but we are clearly not talking about that, but FOMO social media scrolling. There can be good reasons for hyperobsessing over a single issue in life, but you better have a damn good reason for it, like being a successful athlete or chess player or e-sport player or whatever. And it will still be a sacrifice that's only worth it if you are truly exceptional and there's a high chance you aren't. The question is, are those hours bringing an improvement to your life, are they bringing you closer to achieving meaningful life goals or are they a distraction from focus and life organization, and a suppression of quality of life and achievement.
