Today's teenagers

I think that today's teenagers are very lazy. I am shocked at the poor physical health of them. They say they can't exercise because they have to study. However, in my opinion "studying" is just an excuse to avoid doing anything. It is shocking that polish teenagers are on one of the top places in obesity. I know that our government was trying to improve some changes in a meals the schools provide to the students, but personally I think parents should me more involved in the fight against their children's obesity. Where are those times when all the kids where playing with each other outside?
