How is cocaine worse for you than energy drinks?

Let’s pretend the yayo is pure.

After they've taxied through the entire airport, how do their lineup the airline so it's at 0 degrees with the runway? I feel like in the 1-2km it takes to lift off, if the angle is off by half a degree, the airplane will end up in the grass.

I’m learning Spanish with Duolingo and in some ways it’s great and but a major flaw in their system is that there’s no way to seek clarification within the course. A big part of Spanish, apparently, is that the pronouns vary whether they’re referring to a direct object or an indirect object. I’m pretty good with English grammar, but for some reason this concept is one that I can’t figure out how to apply. I’ve tried doing exercises and taking quizzes I’ve found online, but I still keep getting them wrong. Hoping someone can eli5. Thanks!

It makes me wonder how companies managed to stay in business when there was lack of purchasing power and goods usually cost way more than today compared to the average salaries.

So people wouldn't buy a lot of new products and generally products lasted longer. How did companies make money during this period before mass consumption became normal and products started to be sold by the millions?

Does RAM have personal data in it? Is there a place to responsibly recycle or donate RAM?

Just rewatched Breaking Bad and it hit me, how come drug dealers are able to make so much money? Its not like their customers are the wealthiest bunch…

The functional medicine community swears by this test. I had a friend who had one of these done which allegedly showed off the chart mercury on his results. Naturally, his functional med doc wants to treat him with DMSA, which will allegedly “pull” out the metals? I’ve tried to read up on this and it’s above my mental comprehension. Please help so I can explain this to by buddy in a convincing manner!

if people have awful allergies during the day, how are they able to sleep without waking up to sneeze?

So my grandad's already moaning about so called "PAYE people." Just googled it. So employees calculate your tax. You do not pay regular income tax, instead you pay 'PAYE tax.' Is that correct? Do normal workers pay both. Eli5 asap pls.

Edit: thanks geezers for clearing this up. I am 13, pretty interested in economics/politics, with the idea of working for the OBR. All makes sense now.

how to decide which type of anesthesia to use during surgeries; general, local, regional

eg. in prostatectomy why do we choose regional instead of local

I'm hoping this is something someone here can explain simply.

When someone's heart, liver, or kidneys give up, we can do a transplant of the relevant organ, using either a living tissue donor or a deceased one. From my understanding (please correct me if I'm wrong), in most cases, type 1 diabetes stems from or correlates with a non functioning pancreas. So why can't we do pancreas transplants for patients with T1D to either cure the disease or improve those patients' quality of life?

I understand that when you are traveling at lightspeed, time slows down. But what I dont understand is why does far space have a time change? Why does lightspeed correlate with the time of other planets? For example when people say that when you look into outerspace, you can see the past. But why is the time over there, different? Thanks in advance.

I understand how axial tilt causes different temperatures during the four seasons. But during spring and fall, each hemisphere receives about a similar amount of sunlight. So what explains the different weather patterns of spring and fall?

I’m sure this may not apply to all parts of the globe, but autumn is typically associated with wind and rain (and this is also true where I live, in western Europe). So what causes autumn to have different weather patterns (such as high wind and rain) from spring?

not truly understanding if cbd isolate or cbd products can be 100% thc free

I roughly know what it is, but I genuinely think I don’t fully understand the concept (especially when applied to marginalised communities). (I don’t feel any sexual arousal or attraction so imagining people as sexual objects is unthinkable to me) Is it really limited to “seeing people as the objects of a sexual fetish” or does it go beyond that? How is it different from sexualisation? Thank you!

I get lack of memory, because the electric charges that build up can be transferred to long term storage during rest, so being offline helps that process. But how is it that a lack of rest leads to haywire perceptions and phantom surges of electricity by sense neurons/nerve clusters?

You consistently see schizophrenic people draw those “sacred geometry” diagrams that are often like people with tons of lines and geometric shapes going through them.

Is it just a conspiracy theory that happens to stick well with them? Or is it something inherent that identifies these?

Please someone explain what my prof means by her question: “How many entries for the verb give does each of the three dictionaries (Collins Cobuild, Macmillan, and Webster's Dictionary) give?”.

The thing is, I searched up the meaning of “entries” but I don’t understand the task, and there are too many entries to count, or am I just stupid to not get the task?

Thank you very much in advance😭

It seems that the dye was lossely bound to the original clothing, but has bound much more tightly to my towels. There is no sign of the pink fading after several more washes.

Edit to add: I'm not looking for advice on how to get them whiter again, I can cope with pink towels! I am just curious as to why this happens.

There's a myriad of meditation techniques, but I fail to see the difference among them, most of them involving not a lot more (to my untrained eye) than sit still and focus on your breathing. I want to know what's different in the practice of these meditation techniques.

Everything I hear how cow farmers need to take care of their stock baffles me more and more how these were able to survive for so long

A cow needs to be milked every certain period to avoid infections, bruising, death

A cow needs help with the birth of a calf, as its sometimes a process which cant be done by a cow itself

A cow builds up gasses in their stomachs, requiring punctures to avoid sickness, death

And not to mention the parasites, specific diets, and maybe some other things I wouldn’t know about

Was it the overwhelming amounts of land they had conquered?
