The serious mental and physical health problems are real and a societal concern. Everyone "notices" the trends, but maybe it's not you so you just think there's nothing you can do about it and do your best to stay healthy.

Then you have a child and you are suddenly hyper-aware of everything going into the body and brain. Everything they eat, every doctor visit, every time they get sick and what could have exposed them, every word spoken on TV, every friend they have and how they act or how that friend passes along their parents influences, etc.

And suddenly you're very concerned about societal level macro influences on food, medical, etc because those influences are going to affect your child's life.

There's definitely a balance here. Not giving a shit, which seems to have been the tradition I was raised in, is not great. Recognizing problems is good. Acting on all of them is bad. You need to raise grounded kids who can grow into resilience so by the time they're adults they're able to navigate this strange world.

Especially trying to control who their friends are and what they hear. Questionable behavior from friends at younger ages can actually be a good thing: it lets you plant the seed early when your kids still listen to you.
