Good catch! That's a big issue for kids these days - we are not talking about this enought - believe me. To those willing to improve anything I proposed to ask kids do chores time over a bad habit. You can even bargain with them over this - and they will also learn to value their time and also how to better negotiate in the future if you take your time and explain them what they could have said better to win the negotiation. Examples: 10 minutes of room cleaning for 10 minutes of screen time. 20 minutes of reading for 20 minutes of TV. 10 minutes of outdoor activities for 10 minutes of gaming on the phone/laptop, etc. And so on. Adapt everything to what you want to correct/improve at them.
