You know what's funny? One of the "quirky" things about the Fallout Universe is how everything is radioactive because all their tech is based on fission/fusion right? It's meant to be funny like haha yeah our pollution is bad but atleast we're not poisoning ourselves with everything we do. Yet if you sub out "radioactive" for "heavy metal contamination" and "microplastics" etc that's basically 100% accurate to real life america.

Iirc locations downwind or under approach/depart flight lanes of small airports deal with an exposure risk fairly above baseline. I feel like I remember reading then that it ties into modern redlining where there are more minority populations in those areas due to cost of housing and the generational impacts of lead exposure.

So it’s the Cessnas spraying us with chemicals then? I thought it was the ones with the clearly harmless contrails but dang.

The politics and logistics issues holding back lead free avgas are extremely frustrating. I really thought we would have seen that transition by now.

Who knows, maybe it will take electric aircraft to finally put an end to the issue.

I've known a few that were certainly on something...

Jets run on kerosene but higher quality, so yes, the leaded fuel is small prop planes

The danger from leaded fuels don't come from handling, but from the exhaust. The lead becomes breathable and enters the environment, exposing those who lived in urban areas and near roads to more lead than others.

The other poster isn't wrong about airplane fuel being leaded, but that can be misleading because most people don't know that "airplane fuel" and "jet fuel" are different. Jet fuel is not leaded, but the fuel used by small, piston-driven prop engines is.

Most people don't handle airplane fuel

I can't handle it. I get drunk immediately.

Does the lead in the exhaust come down into the air we breathe? Lead is heavy. Would probably be more in cities with airports and under flight paths. Diluted of course, but repeated every day... Perhaps a tin hat or mask would help.

IIRC farm co-ops, rural gas stations, bulk purchases for fleets, etc…

I can remember my grandpa, a career trucker and grease monkey, grumbling about having to use lead substitute in his 60s Ford pickup when I was very young.

We had one gas station in my town in Oklahoma that sold it right up to the deadline. I used it because both my vehicles were built for it.

Cars made before the 70s need the extra lubrication in the valves or the engines wear out much quicker. Engines made for unleaded fuel usually have valve sleeves to prevent excessive wear.

Thats a good point, I always get messed up on small aspects of statistics like that

No idea on lead level, but violent crime has mostly stayed fairly level now, property crime is way down. Something to consider is that rapes are up quite a bit, starting around the time #MeToo went viral. Which IMO makes sense, as more women found the courage to speak out.

That's incorrect. It's correlation, not causation.

If lead were such a direct cause of violence, they should start diverging at the introduction of lead, not long after a notable decline in lead levels. (ok ok not diverge at first, but still have a predictable, visible connection throughout)

Children grow up constantly, and only one of the lines is not age-restricted. If it were to ever diverge while still being a major cause, it'd begin to diverge at the introduction of the stimulus... or rather, start to diverge when the supposed initiating cause was reduced.

As you say, lead is a lifetime problem. If it were to be a tent pole contributor to violence, violence wouldn't have reduced in lockstep basically ever.

Lead is a massive problem and is a toxin, but it surely did not itself contribute to increased violence. Increased stupidity? Absolutely.

I've stopped stressing over perfect grammar and spelling myself. I go for 90% accuracy, that's good enough.

Adhd? "this is how... Sits". I bet your brain sent the command to type "my cat" but made a a cogntivie connection to house sitting based on the sound of your head voice is it tried to generate the sentence faster than you could type. Like it already voiced out to "sits" while your finger were still on "Ho". Idk, I catch a similar mistake weekly. Usually more like typing a homophone or like my fingers just start trying to sound out the word they thought they heard as my head voice has raced ahead.

I'd love to learn more about how communication works in our brains and how it varies between modes. I could see fingers and voice being the same part, but does hearing route a different way? How similarly does the head voice work?

Then, there's the part where something like 10 or 20% of the population doesn't even have a hear voice. And from there, those with the strongest head voice make micro movements of their vocal chords when thinking, while those with no voice make no movements at all.

Fucking la gauge, how does it work

how'se This is how'se my cat sitse
