People are lazy computer and phone addicts. Back in my days and I'm only 29yo, there was a way less fat kids and especially less kids wearing glasses. We used to bully them back then.
Nowdays kids are fat, have glasses and are also dirty even if showers are in every home. They prefer to throw garbage exactly where they are sitting instead of walking a few steps to throw it in the right places.
When i was in school there were literally like 2-3 fat kids in the entire school.
Glasses are pushed on people by the companies and doctors that sell them now. Same thing with braces. Also, some foreign people see them as a status symbol. My GF's nephews both have braces and glasses, their teeth are fine. The prescription on their glasses are almost non existent. They don't even wear them, but they were convinced they needed by the local optometrist.
A lot of the garbage and trash problems these days are cultural. Just go to the Hispanic part of any big City and it's obvious. Hell just go to any place that is filled with immigrants and minorities, you will see everything is trashed out and dirty. That was something i noticed traveling all over Mexico and South America, they have no regard for using a trash can. A lot of places down there don't even clean the bathrooms.
I was in Mexico City a few years ago at a bar. They didn't allow smoking inside so they had a smoking area on the side of the building. Even with trash cans and ash trays everywhere they just threw them on the ground. It was a really nice bar too. I still remember seeing like 100 beer cans and 1000 cigs just tossed on the ground, 5 feet from an empty trash can.
I had a talk with a nice old janitor lady. She is working in schools and told me that girls bathrooms are a way worse than boys ones. I was surprised.
It's been this way for a long time. Women just like to blame men for everything.
Almost every girl i've dated had a trashed out bathroom. Filthy.
