As society evolves, so do standards for what is considered safe and acceptable behavior for kids. When I was a kid, my mom let me ride around in the back of her pickup truck, and go sledding on the street—as long as we "kept a lookout" for oncoming cars, yikes. Of course parenting rules vary from one household to the next, but overall, parents of today tend to be a little stricter about things like internet use, nutrition, and safety.
Also, those of us who grew up in the '90s, '80s and before are pretty lucky to be alive.
