Yep both my parents smoked and you were tramp in the car with them windows rolled up. And they wondered why we bagan smoking in our teens. It was endemic, every one we saw or hung out with smoke. From grandma to parents, aunts, uncles. Hell I still remember our doctor neighbor was a snoker. Why all the appliances and furniture was either yellow or brown. To hide the cigarette smoke I presume.
Doesn't mean they had an easy life ... I grew up surrounded by all my older relatives who looked like this when they were teenagers in the 80s. The thing was .... they all had rough lives and basically childhood (if they had any) lasted about two or three years. Childhood was just never ending terror with rampant alcoholism, abuse at every corner and violent adults making your life miserable. Mix in there that you were expected to work, run errands, stay quiet or get slapped around for even existing. Most of the boys I knew had really rough fathers who beat them for even looking the wrong way ... then they hit 12 years of age and almost by necessity, they had to grow up immediately. They had to grow old, tough, strong, fast and rough because they had to stand up to a previous generation that took it out on them. I remember my older cousin turning 13 and standing up to his dad in a fist fight. It was ugly but he stood his ground ... neither won but he never got beat again.
Funny you should mention that movie ... I just finished watching 'War Games' with Matthew Broderick ... those films just take me back to the 80s. It was a great time because everything was so simple ... but like I said in my previous comment, it was also a rough period because the adults still lived in this world where they weren't so easy on the kids. You could wander around town and if you did something ... anything wrong, chances were high that you could run into an adult that could slap you around and if you told your parents, they'd ask YOU what you did wrong.
We also were able to drive and own cars at 16, which isn't a thing in Canada anymore, and if you pissed off your parents they would throw you out even if you were 15. Parenting was much more lax back then.
What's funny to me is that I looked 20ish when I was about 12 (didn't even have my period yet), like got mistaken for a teacher in 7th grade, but looked about 20 when I was 20 as well. It slowed way down. And now people seem to think I don't look as old as I am (I think I do, by definition) so it wasn't acceleration, we are part of the group aging more slowly.
High school kids now are like when I went. Some look like they should be in elementary school, some look like they are full adult. More of them are fat, but otherwise it's very similar.
