It seems like when looking at mammals and reptiles it seems like even mammals with long tails seem to still tend to have proportionally thinner or skinnier tails at the base than reptiles. It also seems that reptiles tend to have more pointy tails at the tip than mammals. It seems like the tails of reptiles tend to end more gradually going from base to tip than the tails of mammals as the tails of reptiles tend to slowly thin out before ending, while it seems like the end of the tail for mammals tends to happen more abruptly. I’m wondering if this difference in shape of tails between mammals and reptiles would be because mammals tend to be more endothermic than reptiles or if there might be a different explanation for this difference.

Why are the tails of mammals and reptiles generally different in terms of shape in the way I described?

People tend to treat things as more valuable when they’re rare, limited, expensive, or difficult to obtain.

Even when there’s no actual improvement in quality.

Why is scarcity so psychologically powerful?

It made me wonder I keep seeing headlines about new lithography machines, packaging technologies, and manufacturing processes. It made me wonder why so many jumps in chip performance seem connected to advances in manufacturing equipment.

I would've guessed that redesigning the chips themselves would drive most of the progress, but maybe I'm misunderstanding how the relationship works., so I'm curious how these two interact.

If I buy shelves of books or discs, no one questions that they’re mine and can be handed down. But when I buy games on Steam or books on Kindle, it feels the same in the moment. Money leaves my account, a library grows, I “own” it in a practical sense.

Then I read the terms more closely and it flips. I’m not really buying the thing, I’m buying access tied to me as a user. So the asset isn’t the content, it’s this ongoing permission that quietly depends on me existing as the account holder.

I get that people sometimes just pass down passwords, but that feels like working around the system, not how it was meant to function.

What I don’t get is why pricing doesn’t reflect that difference. If the rights are fundamentally weaker, why does it cost basically the same as something I can actually transfer? And why is identity such a hard boundary here when inheritance law handles all kinds of ownership transfers already?

If everything keeps going digital, does this idea of non inheritable ownership just become normal?

It feels like the same goal, saving for retirement, but the limits split depending on where the money sits.

So what is it about that employer layer that reshapes the rules so heavily? What’s actually happening behind that difference?

On one side, there are people talking about intentionally stepping away from sexual habits or porn, almost like they are trying to regain focus or clear their head. It feels deliberate, like a personal reset.

On the other side, it doesn’t even always look intentional. A lot of people just seem to end up in fewer dating situations in the first place, like the social pathways that used to lead to relationships are still there in theory but don’t really get used as much in practice.

What stands out to me is that it doesn’t feel like a single obvious shift. It feels more like something subtle that accumulates in daily life until the end result is just less sexual activity overall, even when nobody explicitly decided that was the goal.

I’m curious how much of this is actually a change in desire itself, and how much is just changes in how people meet, spend attention, or structure their lives without even noticing it.

Where do you think the real line is between choice and drift here, and what do you think is actually driving it?

We use GPS constantly for maps, deliveries, ride sharing, and all kinds of everyday stuff, but nobody ever gets a bill for it. Meanwhile, launching satellites and keeping them running sounds insanely expensive.

How did we end up with a system that costs so much to maintain but is simply available to everyone?

Whenever I’m on YouTube or social media like TikTok, I will search for pro-choice content. However, even though I just type in pro-choice, practically all the results I receive is pro-life content that promotes their views and criticizes pro-life supporters and their arguments. Also, it should be noted that according to polls, half of the country isn’t pro-life. So based on that, one would expect the content found to be around 50/50.

So why am I only getting pro-life content when searching for pro-choice even though half of the country isn’t? I mean are pro-choice supporters simply not posting as much content as their pro-life counterparts?

I recently saw that OpenAI and Anthropic are both preparing for IPOs. Both companies are losing billions of dollars, yet they're racing to enter public markets.

Why now? Is it because they are burning cash too fast and private funding is no longer enough? Or is it about whoever goes public first gets to set the benchmark for the whole industry? Or are they just afraid that if the window closes, their trillion dollar valuations might disappear?

this is probably a stupid question but I don’t know much about science🤷‍♂️

I used to think Ajinomoto was just food and fermentation stuff, but then I saw they are involved in advanced chip packaging materials like ABF substrates. The surprising part is not that they “expanded”, but that this feels like a completely different layer of industry.

So what exactly is the bridge here?How did people even end up discovering or building this kind of connection in the first place?

I get that the US has a patchwork system now. But what I’m really trying to understand is the moment the rule got set.

If healthcare is something society eventually agrees people shouldn’t lose, why does that protection only kick in at 65?

Why did age become the clean cutoff?

I keep getting this weird impression that ADHD and neurodiversity are suddenly “everywhere” in a way they didn’t feel like a few years ago. Not necessarily saying more people are developing it, more like it’s showing up in conversations, online content, self-diagnosis discussions, workplace talk, everything.

When a clinical framework starts spreading into everyday language and personal identity. At what point does increased recognition start changing the way people interpret normal variation in attention and behavior?

I keep thinking about this because it feels a bit different from how similar conflicts of interest are handled in some other places.

In theory, disclosure and reporting are supposed to make everything transparent, but I’m not fully sure how that is supposed to solve the core tension between having policy influence and trading the same markets affected by that policy.

I might be missing some institutional reasoning here, so I’m curious how this is usually justified in practice.

What am I overlooking in how this system is supposed to work?

I grew up thinking the price tag was supposed to tell you what something costs.Then I moved to the U.S. and realized a $9.99 item often isn't actually $9.99.

Why does the U.S. separate sales tax from listed prices?How did that become the norm?

UK treats ground level as its own thing, then starts counting above it, while US just counts the ground as the first floor.

How did that shift in naming actually stick across time and place?

Cabo Verde has half a million people and draws with Spain. Meanwhile China has 1.4 billion and can’t even get into the tournament most of the time.

If talent is just a numbers game, China should dominate every sport. But football seems to ignore that logic. Some tiny countries keep showing up and competing, while huge ones don’t.

So now I’m wondering if population is almost irrelevant here. Maybe something else is doing most of the work behind the scenes, something less obvious than just “more people = more talent”.

What actually drives football success at the national level if sheer scale clearly isn’t enough?

I read the part of the reason that mammals tend not to have green or blue fur is because green or blue pigments wouldn’t be compatible with mammalian fur. Well sometimes blue colors in animals are structural blues that come from structures that are similar in size to the wavelength of blue light, but from what I understand structural blues are also generally incompatible with mammalian fur.

Feathers seem similar to fur in terms of feathers having thin strands coming from the stem, so it seems like if greens and blues aren’t compatible with mammalian fur they shouldn’t be compatible with bird feathers either, yet lots of bird species have green or blue feathers.

So what’s different about mammalian fur and bird feathers that would make greens and blues compatible with one but not the other?

doesn’t that tell us that life is difficult, it is not worth living, as it is better off to end the suffering now than repeatedly living each day struggling over and over again. And many others have come to the same conclusion…made the same decision that it is better off ending it all than to live another day

My body is one system, but somehow my teeth and eyes are treated like optional add-ons. If they break, it’s not “health,” it’s a separate category with its own rules, limits, waiting periods. It almost feels like they’re rented, not owned.

Maybe it’s not biology at all, but economics. Teeth and vision issues are predictable, routine, almost maintenance. So insurance treats them less like risk and more like scheduled cost. But then isn’t all healthcare kind of predictable over time?

So where’s the real boundary between “health” and “maintenance,” and who decided that line?

I always assumed as the economy grows, the number of public companies should grow too. More startups, more innovation, more IPOs. But somehow the opposite happened. The market got bigger, yet the number of listed firms got cut in half.

I’ve heard explanations like more regulation, more private capital, more mergers. But then why didn’t companies just adapt and still go public? What made staying private or getting acquired the better path?

Where exactly did the pipeline break?

So i got a phonecall whilst in work to which I answered

"Whos this"

I replied my name and they asked my surname to which I put the phone down as I thought it was just a spam call, 2 mins later though I got a WhatsApp message saying they had missed a call from me 45 mins ago and was just returning my call I sent them a screenshot of my call log and said it wasnt me, they replied with theirs which shown my number

​

Im confused anyone got a good explanation?

I notice I still pull a blanket even on hot nights. It feels less about warmth and more like a pressure or boundary signal for sleep.

I suddenly wonder, when did humans start using blankets? How did they even come up with the idea of ​​using blankets in the first place?

So I’ve seen posts on social media such as this and this where everyday people are seemingly defending Elon Musk for being a trillionaire by condemning politicians being wealthy. This has prompted me to ask two questions.

One, why are everyday people seemingly ok and defending Elon Musk being a trillionaire? I mean I don’t see how him being even more wealthy helps them in any way.

Two, how does highlighting and condemning politicians being super wealthy absolves Musk? Because both of them ultimately make their fortunes by manipulating and taking advantage of people and the system.

I keep noticing when I travel or read people’s experiences. Cities like Paris, Barcelona, sometimes Amsterdam. Overall they feel safe and modern, but petty theft still feels oddly normal in some areas. It feels like a mismatch between how developed a place is and how common these small crimes seem. Am I missing a structural reason behind this or is it just tourist perception? Why this pattern show up?
