To expand on the HEPA vs. CADR (clean air delivery rate) thing:
If you were sucking air out of a room and passing it through a pipe to another room, with just one filter, then you would want as good a filter a possible, a la HEPA, with it's 99.97% or whatever filtration. You might want this for your HVAC system, especially if it's bringing outside smoke-ridden air -- if your HVAC is strong enough to push air through a HEPA filter, which it might not be.
But a purifier off Amazon sits in a room, sucking in air, filtering it, spitting it out, and sucking in more air... some of which was already filtered, because air mixes. Here, filtering some air very well matters less than filtering all the air ASAP. Thus the idea of a MERV 13 or 14 filter taped to a fan, or the bigger Corsi-Rosenthal boxes with more filters (thus more area, lower pressure.) MERV 13 is filtering maybe just 50% of the worst size in a single pass, but by cycling a lot more air in a given time, the setup can supposedly clean a room faster than a similar sized HEPA purifier. And for much less money, as box fans and filters are generic items. While as the video clumsily indicates, some purifiers have become overpriced brand items.
My own advice: if you don't do a filter/fan thing, look at CADR/$. The Levoit Vital 100S has 143 CFM (cubic feet per minute) for US$120 right now, $140 list price, with electronics for scheduling and such. The Core 300 is $100 for 140 CFM. So those options are 1-1.4 CFM/$. If you look at other models or brands, you shouldn't accept less than that, especially if it means paying for outright harmful features like ionizers. You probably won't get much better, though I think I calculated 1.6 for some model.
Paying more for quiet might be worth it, but good luck. Sellers tend to advertise their high-setting CADR and their low-setting noise rating, which is not very helpful.

The actual line in the Prologue of Fellowship is
"And laugh they did, and eat, and drink, often and heartily, being fond of simple jests at all times, and of six meals a day (when they could get them)."
There's no mention of second breakfast, nor really any other mention of additional meals, apart from Two Towers when Merry and Pippin have a second lunch to keep their friends company at Isengard.
LotR is absolutely full of references to breakfast, though. Tolkien seems to have assumed breakfast, lunch, and a large supper as the standard meal plan. (Yes, I just did a bunch of text searches.)

@ahmedel-sayedosman2951 There's also the opposite of recessed windows: latticework covered balcony, Mashrabiya.
Windcatchers are pretty neat, though I think fans are pretty low energy compared to the rest of a developed lifestyle (like the fridge.)
Just lowering the temperature of air would actually raise the relative humidity: cold air can hold less moisture before being saturated, so a constant amount of moisture would get closer to saturation. This is why clouds form as air rises and cools, the air reaches the dew point and moisture condenses. Air conditioners actually remove moisture as well, delivering cool dry air.
I think a good future still has lots of air conditioning, but we should also build so it's needed less / doesn't have to work as well. Which means (in the US) upzoning so more people can live in dry moderate climates (like California and the Pacific coast, as well as using tricks like awnings, covered balconies, cross-ventilation architecture, etc.
(Gven current trends, we also have to plan for the outside air being full of wildfire smoke, so not actually healthy to bring indoors without filtering.)

@QTwentyTwo
Amazon Fresh:
2.79 for a Lunchable ham and cheese "cracker stacker", 340 cal, no fiber, 11 g protein. and a lot of the calories are from a cookie.
1.33 for a hotdog ($8/6 pack), 190 cal, 10 gr protein.
0.17 for a slice of whole wheat bread (2.79/loaf, lol), 100 cal, 3 g fiber, 5 g protein.
So $1.50 for a hot dog + bread that's equal in calories (290) to the Lunchable minus cookie, with more protein and fiber. Or double the calories to 580 for about the same cost as the Lunchable.
Not that that's a great lunch either but it's cheap and convenient and _better than Lunchable_.
In reality I'd probably aim for a ham-cheese-lettuce sandwich, hell that's what my father gave me half the time (other half, PB&J with whole wheat bread and natural peanut butter) but that's slightly more research work.

In this case it's not "corporate greed" nor capitalism, unless by the latter you simply mean supply and demand. If supply is fixed and demand goes up, price goes up. In a sense, US wings are "overharvested" now the way lobster was -- not literally going down in supply, but demand outstripping supply.
In the US, breast is the most expensive chicken part (after the modern wing), because Americans are scared of the fat of dark meat or something. In Japan, dark meat is like twice the price of breast, because they value the flavor more. No especial greed, just different demand, thus a different market-clearing price.

@rambcio4199 "Ofc u dont prefer worse quality, worse safety, worse aerodynamics, bigger weight, worse performance, worse clotches"
If the last one is supposed to be clothes: most people prefer biking in their casual everyday cloths, not special biking outfits.
As for 'quality' and aerodynamics and performance, there are other criteria, such as safety, which you've misattributed. Also theft risk. A cheap heavy thick-wheeled bike gets me various benefits compared to an expensive road bike
* low temptation for theft
* low financial loss if it is stolen
* riding safely over gravel and potholes and road debris
* less likely to get the tire caught in a slit like hitting streetcar tracks at the wrong angle
* a more comfortable and safer posture
Also, commuters/utility bikers are often carrying things. I doubt the aero benefits of a road bike matter that much when you're hauling two large shopping backs in your rear baskets.

"It doesn't work except for all these places in the real world where it works."
Width helps. Also, well, who's biking? Where you see really mass biking, like Netherlands or Japan, most bikes aren't that fast. Heavy bikes, upright posture, no helmets, speeds around 10 MPH; not 20 MPH road bikes.
Having more separation is nice, when you can, but if you can't, it's still better to have a path than not. If you're on a fast bike, just slow down. Or if you want to keep going fast, stick to the roads.

I just did a websearch on that. Ignoring Richard Gabriel who apparently thinks he can talk about Moses as a historical general, the consensus seemed to be that he couldn't. He had 40k surviving troops, Rome had 20k defensive field forces, 200k civilians behind walls, and the ability to _raise even more armies_. And to feed them, while Hannibal didn't have reliable supply or a port he controlled. And Rome still had loyal allies even after Cannae. So trying to besiege Rome would have been facing superior forces, without food, and open to getting flanked by Roman allies.
So he ran around trying to get more of his own allies or secure a port.
They also say Hannibal's goal was to break up Rome's coalition, and/or make Rome sue for peace due to humiliating defeat. Rome's goal was to not lose, no matter what. And, as a large republic, had very deep pockets of money, manpower, and morale to just keep going. Kill 8 legions? They'll raise another 8, and change their tactics.

@aokiaoki4238 I have read multiple histories of salt and spice. What you say is all wrong.
"it was cheaper to load mined salt from India and China."
No. Europe had multiple salt mines like Hallstadt and coastal salt-producing towns like -wich towns in England. Used for preservation, it's a bulk good, not something you would transport from India. The real reason for the spice trade was, y'know, _spices_. Black and long pepper, cinnamon, nutmeg cloves... also Chinese silk, giving the other name, "Silk Road".
"Black pepper was cheap"
Black pepper was worth its weight in gold in Europe, until the age of navigation started to cut out the middlemen. It is used for flavor, not preservation.

I have a really old structureless Trader Joe's canvas bag, possibly from the 1990s. Also a few newer totes from somewhere. If I'm going shopping I bring my backpack, which usually has 3 more bags in (the TJ sack, a black tote, one of those new thick plastic bags that the store charges 10 cents for.) On checkout, fill the backpack and as many bags as needed, walk home. I also have an old-style thin plastic bag in my pocket for impulse shopping sans backpack.
Around here, thin plastic bags are banned from supermarkets, though some takeout food still uses them. I did tend to use to accumulate them, but they were re-usable: garbage bags, food wrapping bags, insulation for making yogurt. By contrast, paper bags (even with handles) had no re-use for me (too awkward to want to bring back to the store), and the handles tended to rip off anyway. And as the video hinted, they're not obviously better than thin plastics anyway.
The one nice thing about big paper bags was that my bike had folding baskets of just the right size for one, so I could bike home with a full backpack and two full bags, with stuff held in by the structure of the paper, better than plastic could do.

@svr5423 "step out"
Yes, that's what a balcony allows me to do. Step outside casually, even in pajamas.
Without one, I have to get dressed, put on my shoes, get my keys, leave the apartment building -- perhaps taking an elevator ride. Possibly putting myself out on a public sidewalk, rather than 'my' balcony to sit and read. And then reverse all that to get back in: let myself into the building, take the elevator, walk down the hall...
There is obviously a huge difference in ease.
Balconies also allow having some potted plants, or put out clothes to dry. So they're practical as well.

Wiki
"A distinction is sometimes made between "hot cocoa", made from cocoa powder (ground cacao beans from which much of the cocoa butter has been removed),[22] and "hot chocolate", made directly from bar chocolate, which already contains cocoa, sugar, and cocoa butter.[22] Thus, the major difference between the two is the cocoa butter, the absence of which makes hot cocoa significantly lower in fat than hot chocolate"
And presumably thinner as well as lower in fat.
I had "hot chocolate" at a cafe once, and was surprised; it is indeed much like simply melting down chocolate and mixing with some milk, if that. Thick, rich, probably more calories than you want to think about...
"European hot chocolate tends to be relatively thick and rich, while in the United States the thinner instant version is consumed more often... In Germany, hot chocolate made by melted chocolate (Heiße Schokolade Wiener Art) is distinguished from those made from powders (Trinkschokolade).[28] It is often served with whipped cream on top.[28] "

I'm not sure when, but Athens did keep some elections, for generals (gotta actually be competent) and treasurers (gotta be rich enough to not steal from the state, was the idea. or to be able to get money taken back if you did.)
But yeah, selection by lot for the Council of 500, the large and important juries, and various 10-person "get something" boards.
OTOH, while Athens may have given us the term 'democracy', and a form of it which sadly hasn't had many imitators, it's not like all forms of democracy simply descend from it. The Roman Republic is about as old, and evolved in vary different ways. Carthage elected its leaders too. And modern representative democracy evolved in its own way, not obviously owing much to Athens.
I've seen it said that Greek city-states all had magistrates, council, and popular assembly (and you see these in Rome and Carthage too), and varied in how powerful each component was (also whether the magistrates and council were hereditary or elected or what) and exactly how broad the assembly was.

I believe the Islamic calendar is the only pure lunar calendar in the world (plus a Javan calendar derived from it.) Every other 'lunar' calendar is lunisolar: based on lunar months but with one mechanism or another to keep it roughly synchronized with the solar calendar (or put another way, with the seasons.) Most people want spring (and planting) to be at least roughly the same time on their calendar, while the Islamic calendar freewheels across the year.
I've seen it suggested that pre-farming peoples would have cared about calendars too, for e.g. timing the migration of animals. Also that such calendars, and early farming calendars, would have been "the year starts in spring" (ice melts, first leaves, whatever), then counting lunar months into winter, when time didn't really matter, and resetting at the next spring. So basically a self-synchronizing lunisolar calendar.
I'm skeptical of the Hindu calendar being based on Jupiter; Chinese does seem to have a connection but I think more complicated than "zodiac".

"When commercialism and industry is centralized, you get large urban sprawl"
What? No, those have nothing to do with each other.
"bike paths should be used as a means of work home transportation,"
Bike paths are a means of transportation, period. Jobs, shopping, parks, schools, whatever.
Yeah, in a big urban area, many will find the distances too far to simply bike to work, though they might bike to transit to work. But work trips are only like 1/3 of all trips, you know? Majority of trips are short. Even in the US, half of car trips are under 3 miles.

I lived in Osaka for 3 months, and took away all the same lessons and impressions (many of which I've been sharing in youtube comments for the past 5 years.) Osaka does even better, 25% of trips by bike. And note that this is with much worse weather than the Netherlands, also larger cities (so home-to-job distance will be bigger) and public transit that isn't bike friendly.
Your Tokyo 'wide sidewalks' actually looked pretty narrow to me; I think the standard for arterials is supposed to be around 4 meters, or 13 feet or so. And in Osaka, most bikes along arterials were on the sidewalk/multi-use path (though many stayed on the local streets, too, of course.)
Cynically, one reason more people don't look to Japan is that it's distant and more foreign; some would even invoke racism. But to be fair, I'm not sure how much we can learn from Japan's streets, except for new development. There's no quick path for turning a Chicago local street of 66 feet (right of way) into Tokyo street of 16 feet. For existing cities, streets are laid in already. We can re-arrange the asphalt easily, but I'm told moving curbs is expensive, and when buildings are already 80 feet apart wall to wall, there's not much we can do... unless we start building small buildings in the middle, creating two narrow streets out of one wide one.
Density: NYC has a lower density of 10,000/km2 due to State Island and outer Queens. 15,000 is right there with Brooklyn and the Bronx or inner Queens. Paris France is 21,000.
Also, I feel you should credit NJB a bit for title and "cities aren't loud" meme drop. :)

1. As far as I know, not in general. (The video does mention a 5000 yen rebate for seniors to give up their driving license.) It's just sensible to bike when you have short trips and biking is cheap and safe. If you could bike at 3x your walking speed with minimal risk, why wouldn't you bike?
There are dis_incentives to _driving_. Expensive gas, maybe harder to get a license, and above all, parking. No curbside parking and minimal parking mandates, so if you're driving in a city like Osaka or Tokyo you _will be paying to park everywhere. If you rent an apartment then you have to show the police that you've leased a garage parking space before you're allowed to buy and register a car, and that parking could be 30,000 yen a month.
Also, where I lived in Osaka, most of the supermarkets around me didn't even have car parking. One was off-street, only accessible by foot or bike (with a huge bicycle hangar). One was on the street but on Street View I don't see any car parking, while there are bikes surrounding its two open walls. The other two were in the basements of train stations (and their associated malls); there were (paid) parking garages but you'd still have to get your groceries upstairs and into an adjacent building.
And all four of those were within a 8-12 minute walk of my house -- my tiny house on a tiny lot, which did not have any car parking of its own, on a tiny street which you could drive down _very carefully_.
So, you could walk or bike; drive to and pay for a garage and then walk down to the basement, in probably more time than just biking or even walking over; or drive further to some hypothetical supermarket further out that might actually have convenient car parking. Or in my case, walk from home to pick up my car from a garage or parking lot, to then drive...

Wow, and here I thought my Airbnb in Osaka was impressively small. That was technically a detached 2-story house (with like 3 cm of air gap from the next building), long and narrow and tapering. Kind of 3x7 meters except I don't think the widest point really hit 3 m. Still, total of 30-40 m2. Narrow and very steep stairs (ladder, really); I ended up just leaving my luggage downstairs and only going up to sleep, so most of the upper space was wasted for me. No tub, just minimal toilet and shower stall. Two gas burners, two sinks next to each other, mini-fridge, clothes washer.
For just me, living out of my bags and laptop, it was mostly fine; if I had a friend over for dinner and anime, we had to maneuver around each other a bit.
Was about $1000/month in 2019.
One objective complaint about such narrow places, stretching along a street, is that they have no depth. Any sound from the street, like old people talking to each other at 7 AM, is a short distance from your head. I guess longer distance once you go further up. But that was annoying.
