text: Laying around all day could cause health issues. If someone just lays around all day they might become very unhealthy and not get the exercise they need, but if you are active and doing activities, that will change the situation for you completely. Moving around is good for ones health. If someone is laying on the couch, scrolling through Instagram all day and never getting up could get them Diverticulitis. Being unhealthy like that could cause serious problems, definitely at such young age.
