They don't, and I've never heard one confidently say they did.
Educated guesses based on what they do know and what they think they know about behavior, anatomy, etc. are common and often proven right and proven wrong by later research.

Partially, for sure. Psychology is pretty complex, but definitely a component.

Reply to comment by [deleted] in ELI5: Where did my first living cell come from? by [deleted]
Your mom's egg and your dad's sperm both contain half of the DNA it takes to make a person, including the DNA instructions it takes to run a living cell. Other cells have a whole copy.
Before that, those cells (egg and sperm) are supported by the body they come from, and their half copy of the DNA only has limited instructions for "running" the cell.
When the egg is "fertilized", the two half copiesf the DNA combine, finding their other half of the code, matching up, and arranging themselves into functional "genes". These genes contain instructions for just about everything; stuff that makes you related to your parents like hair color, etc, but also all the instructions for starting a human from that one cell.
There are instructions for cell division: how many, how fast, how much? .... Instructions for cell differentiation: how many of which kind of cell, where? Instructions on how cells arrange themselves: form a tube, or a ball, fold it in inward, you build this tissue, you build that tissue, you make heart muscle, you make a spinal cord, grow a spine with a tail, but then stop and re-absorb most of it!
After a while, you have a developing fetus that grows into a baby, if things go right.

Yeah, there used to be lions and leopards all over Europe during the ice ages. They may not have been that far north, though, because there were glaciers covering that far.
We used to have jaguars in Canada overhead in N.America.

Slapping contests remind me of an old video I saw with two drunk hillbillies sitting on patio furniture in shorts, taking turns zapping each other with electric bug zappers.
If it makes money, I guess I'll start a league for apple-bobbing in hot grease.

Like everything else. You get it, and survive.
Also, plague did mutate, and morphed through history. When people got bitten by fleas it wasn't as deadly (still bad) as when transmission person to person (by coughing) became possible.

Just by observation.
Even without germ theory per se, back as far as ancient China, Mesopotamia, and Egypt, people could tell that exposure to SOMETHING caused disease. Night air? The moon? Miasma? Insect bites?
Keeping the sick away from everybody else, and noting that people got sick around sick people doesn't require the direct knowledge that micro-organisms are responsible.

That clause isn't bad. It became famous for how bad the rest of the novel was, becoming a literary in-joke.
Bulwer-Lytton wrote incredibly long, convoluted sentences. His rambling metaphors often seem like he wrote himself into a corner for three paragraphs, then ended them abruptly. His stories are full of heavy-handed philosophy and on-the-nose comparisons. His prose is invariably grandiose.
Stuff like that.

Yes and no, but only as it applies to chokes. Spiking intra-cranial puts you out before the lack of oxygen could.

Reply to ELI5: Why can people pass out after being choked/strangled for only a few seconds when the average person can hold their breath for much longer? by nickelbop
While a choke does cut off/limit oxygen supply to the brain by limiting blood flow, which is air-flow as some have said, something else is usually going on.
The jugular veins are easier to occlude than the deeper arteries are, especially the internal carotid pair and the vertebral artery in the posterior neck. So, a choke actually TRAPS blood in the head, preventing it from flowing out at the same rate it's being pumped in.
This creates a spike in intra-cranial blood pressure, and THAT causes the KO even aster than hypoxia would. This can take, 3-4 seconds.
If it takes closer to 12-15 seconds, that's probably more from hypoxia.

That has always been a fact, but it is clearly not what is being represented here.
The article concludes that, while myocarditis is possible from vaccine, COVID infection is far worse oth in severity and incidence. OP waves the paper and screams "They lied! The vaccine causes myocarditis! Says so right here!!" Figuratively, of course, but check his post history......
So, no, that is NOT "all this is saying."

Reply to ELI5: How does salt seemingly hydrate you and dehydrate you at the same time. They always say you need electrolytes (salt?) for hydration, then why can’t we drink sea water? by TriCombington
You CAN drink sea water. Your body would use both the water and salt. But, you just can't drink very much, and not without drinking something else, preferably nu e fresh water, to compensate and help it process the salt.
Like with most things, the poison is in the dose. Even at ypur most dehydrated, salt water from the ocean is too salty, way too salty, and not only will it wreck your kidneys, but without the other electrolytes beside sodium muscles and nerves won't work.
