Yes, that's it!

There's nothing arbitrary about it. The definition isn't dated or narrow, it's properly specific.
>Again the use of battery to denote a singular object is well established and 100% valid
Yes just as a truck is a singular thing, that is made up of other things. Nobody is arguing different.
> You can’t ignore the most common usage to try and create a false oxymoron
How often are you speaking of the cell count on batteries to alledge what the most common usage is?
And again, what do you think strictly speaking means? Might it mean according to the strictest definition?

So it's more like the dose that 50% of people can survive or dose that kills 50% of people

Off road capable vehicles are like indoor outdoor basketballs, they don’t actually work well outdoors. They’re certainly better than indoor balls (regular cars), but if you want something that’s actually useful in rough terrain, you want something that’s specifically built for it. Not something that claims to do both.

I'd like to add to this: While benzos on their own are rarely fatal if overdosed, withdrawal from them is one of the most dangerous forms of withdrawal, and can itself be fatal.
I've known some people who would read that they're so rarely fatal high doses and think, "wow I can take all the benzos I want! Benzos are safe!"

Alright, maybe an example that you should know what it feels like, you know when your foot/hand/arm is dead asleep and you try to move it but no matter how much effort you put into it you just can't get it to move until it's not asleep anymore? Like that.

Etizolam got banned in a few places because it’s more well-known. The tough part about figuring out what’s banned and what isn’t is that we’re often dealing with multiple country’s lists of substances; even if a substance is legal here, it may have been banned in the country it’s coming from and vice versa.
A lot of the more popular ones got banned either in the NL or the US recently, I believe, but there’s always another obscure one popping up. Seems like a lot more etizolam analogues than straight up benzo analogues lately.

Their bodies are also more mature, so they are able to do the things they need to do right away.

I believe that Is tied to the fact that when a status epilepticus goes on for some time, the GABA receptors start being pulled away (in a process called endocytosis) from the synapses. So You Need to rely on drugs that use other mechanisms to get the neurons to stop firing. Happy to be corrected if someone has more up to date or precise info

They’re evolutionarily hardwired to do so for the best chance of survival in their habitat. Their brain isn’t as complex as humans so it doesn’t need as much time to mature.

Reply to ELI5: How do large ships parked themselves at docks before invention of tug boats? by crenshawcrane
I work at a facility that handles large barges, as well as ships. With the ships, tugs are the main force finessing it into place but also the ships own power source can be used to reverse thrust and ‘apply the brakes’.
The barges are likely more similar in size to that of ships in times before tugs were around to help. Assuming the weather is not too rough (wind can wreak havoc in the process, and it’s more safe for them to be at open sea than to attempt a landing) the barge approaches the dock very slowly, and the tug that has towed it there is also a factor here but the large, heavy ropes that are used to tie the barge up to the dock can be used to ‘apply the brakes’. These ropes are attached to the barge, and a worker on the dock puts a wrap or two around a cleat and is able to apply enough tension in the rope so that it slips just enough for the situation. If he holds the tail of the rope taught, the knot on the cleat gets tight, and the rope gets tight and stretches (the diameter of the rope might be 4 inches in its static state, and as it stretches, the diameter reduces dramatically…. This always freaks me out because I know that if the rope breaks under this kind of stress, it’s like a rubber band on steroids and can literally cut a man in half) as the barge slows down. He can loosen his grip and allow more rope to slip if necessary.

To put it mildly, your post is full of lies and blatantly wrong statements. Most of them not even close even if one rounds the numbers very generously.
> It mimics the way cells divide
No.
> the ratio between any successive numbers gets closer and closer to Phi
Yes but that is definitely not behind the hype. I can write down a lot of sequences that converge to whatever number you like.
> the western musical scale is based on the sequence with one octave having 13 notes and a scale having 8 notes
It is actually based on powers of 2^(1/12), namely those close to rational numbers.
> tons of architects over many cultures have used that ratio in their buildings
Tons? maybe one in a thousand, at best. Which is not because the number is great, but because they fell for the hype.
> Our DNA strands measure 34 angstroms long by 21 angstroms wide for each full cycle of its double helix spiral
This is completely random, measure it with any other unit and it becomes wrong. And it is completely false, too. Their length is way higher (in the order of centimeters per chromosome!), varies between chromosomes a lot, and more. And googling says it's actually 18 Angstroms in diameter, not 21, but whatever, that is random at this point anyway.
> the ratio between our moons radius and the Earth's radius is phi
Just no. Don't invent random things. The ratio is ~3.667, what the heck did you even smoke to confuse that with phi? At least check your claims sometimes?
Edit: fixed quote.

You also have to consider the volumes of water needed by drought stricken areas like the US southwest.
California uses 1.8 million barrels of oil per day.
California uses about 91 gallons of water per day per person. That translate into 84.5 million barrels a day.
​
The construction costs, and engineering required to moved THAT volume of water across the country make it completely unfeasible.

I know it doesn’t mean “I’m going to arbitrarily ignore other definitions of the word to focus on an outdated and/or narrowly used definition”
Again the use of battery to denote a singular object is well established and 100% valid. You can’t ignore the most common usage to try and create a false oxymoron. That’s like saying “Well if you ignore all the points the other team scored, technically I won, even though the final score was 100-1 then”.

A tree well is an area around a tree that receives less snowfall than the surrounding area, due to the foliage of the tree blocking it. This results in a pit or "well" in the snow around the tree.
Tree wells are dangerous even in non-avalanche conditions because someone can fall into them and be unable to escape. Falling into a tree well can be lethal in the worst cases. I suspect they would be particularly problematic if you were washed into them by an avalanche because it could bury someone even deeper than normal as you would essentially be pushed into a hole and then the hole covered up.

Even more important:
Let's say you now want to force John to lend you his bike. He doesn't want to. If you're the one who decides that this person can't use marbles, suddenly you stop him from trading with everyone else.
It is really good to have that power.
The issue occurs if you abuse your power too often, then guys will say "let's skip marbles, how about we also do trade in Sports Cards?"

What do you think the phrase "strictly speaking" means? And how often are laymen talking about the cell count in a battery? I wouldn't say the topic is broadly discussed by the general public at all. And in cases where it is the definition and understanding indeed dictates a single cell battery an oxymoron.
