Some example could be they have house to pay, they need to give the children food, and their certainly very tired after couple hours of working. For adolescence, they don't have that much responsability, they go to school, learn, study and prepared their future. Very old person does not really have a high stress level, their children take care of them, is their time to relax. Middle and high schooler have stress with study homework things related.
