If anything, behavior that is based so much on learning is the unusual outlier. In the animal kingdom, primates (and mammals in general) are strange for how much they have to learn. Its far more efficient to have neural circuits already designed for the skills you will need. The tradeoff is that we are incredibly adaptable to the environment and culture that we live in and can continue to add skills and nuance to our repertoire for many decades. I may not have been born knowing how to navigate the Sargasso Sea, but at least I could learn how to post comments on Reddit.

Offroad vehicles are typically designed to go slowly over rough terrain. Their shape does not matter for aerodynamics, and being boxy means the most storage space for any given footprint.
At the opposite end of the spectrum are sports cars and cars designed for efficiency, such as the Chevrolet Corvette and the Toyota Prius. Those still have to have the space they need to do their jobs (space for two people plus a large engine for the former, space for people and cargo for the latter) while still being good aerodynamically.
Then, you have white vans, lorries/tractor-trailer trucks, box trucks, etc. Those are designed for the road, but need to maximize cargo space. The fronts tend to have as much aero design as they can get away with, and the sides often have skirts, etc. There is a limit to how efficient the design can be, but if you can carry enough stuff in the back, the efficiency matters less.
Back to offroad vehicles, that is why they were originally boxy. Nobody cares what shape offroad vehicles, bulldozers, or forklifts, were. Over time though, those offroad vehicles became the luxury vehicles as well, and space inside luxury vehicles matter. So, even while it is possible to try to make them less boxy, people have long associated "boxy" with "good offroad", which draws people to buy these box-vehicles, even when they will never take them further offroad than parking on the grass at the park. (On a side note, this has caused people who ACTUALLY need large offroad vehicles to be able to get them used more cheaply than before, and often in better shape because these "road queens" never left the road.)

Can you tell us more about the condition? That sounds terrifying. No problem if too personal. Good luck friend

Reply to ELI5: How do large ships parked themselves at docks before invention of tug boats? by crenshawcrane
It is surprisingly easy to move even a relatively heavy ship just by pulling on ropes.
Distance is speed times time. Speed is acceleration times time. Acceleration is force divided by mass. A modest force (let's say 50 kg-force) applied to a large mass (let's say 100 metric tons) for a modest amount of time (let's say 20 seconds), is enough to accelerate the mass to a slow but sufficient speed - in this case, 10 centimeters per second, if you ignore all friction. Then wait a bit, and after 10 seconds, the boat/ship has moved a meter.
Of course, water is low friction, not no friction, so it'll take more force and you'll quickly reach a max speed, but it does work in practice.
This video shows a car doing that with a massive modern ship, but as you can imagine, you can do the same with a couple of strong men pulling on ropes.

This is true, also general size of chest cavity etc. But they don't know much else. There could be all kinds of obstructive tissue, convoluted airflow pathways, muscular limitations and just about any other barrier you can imagine. It's entirely possible for a big barrel chest and other appropriate anatomy to produce a cute little whistle or some kind of baby dinosaur from a Hollywood movie trill.

Reply to Eli5 if the universe is expanding, then why isn’t the earth, and everything in it (us) getting measurably bigger too? by Far-Contribution-632
Imagine you are standing in one spot wearing roller skates. On your left is a 250 lb NFL lineman. On your right is a 50 lb child. They each begin pulling on you in opposite directions. Which way will you go?
The universal expansion is like the 50 lb child, gravity is like the 250 lb lineman. At distances smaller than galactic clusters, gravity wins.

The box shape provides more interior room to hold things, especially if you're spending many days outdoors. The roof is flat so you can put more things on top. Lastly, the shape helps prevent the vehicle from rolling onto the roof like an upside down turtle.
There are downsides however. A box is not aerodynamic so the mileage is poor. At high speeds, the air hitting the box is loud. Mileage is getting regulated by countries for new cars. Comfort is what people are interested in for a daily driving car.

I'm definitely going to look into that, thanks man. It is a pain in the ass like no other trying to convince these doctors that no, i'm not a drug addict, i just tolerate opioids and plenty of other meds well.

You explained that ELI5 isn't literal. But I was clearly asking if the clarification you're making is necessary within this kind of explanation. Was my technical inaccuracy negatively impacting the explanation I gave in any way?

Have you tried a genomind genetic test for medication efficacy? My mom has lots of similar issues and while it seemed like BS at first, the results have actually been really helpful for her to navigate different pain medications and have accurately predicted which ones she'll rapidly metabolize and which ones will stick around for longer.

I do sometimes when I have to swallow a pill. My brain forgets how to swallow long enough for the pill to melt in my mouth and ruin the next hour of my life.

Third most potent benzo I’m aware of. Flunitrazolam and flubromazolam seem to be a bit more potent, but clonazolam was much more popular because flunitrazolam only lasts like two hours and flubromazolam was way too hypnotic for normal use.

I know you can read and write and be appreciative and are smart enough to access reddit and empathetic enough to share your story of survival to help someone understand. Dont discount those qualities and abilities. Considering humankind they do move you up "in the ranks".

That's 950 milligrams, almost ten times a standard dose of Valium.
As someone trying to abstain, I just use 30 mg a day spread every 6-8 hours out when I withdraw.

Reply to comment by [deleted] in ELI5: Why are off-road capable vehicles so often “Boxy?” by [deleted]
That’s why I said “they’re certainly better than indoor balls (regular cars)”. I was making a point that just because they’re better than your average Prius doesn’t mean they’re actually good on rough terrain. It’s like saying you’re a professional basketball player because you can whoop a 4th grader 1v1.
