beetroot juice was a few years ago and it's for a different purpose - nitric oxide to relax smooth muscle in the airways. the red recovery drink at recent events is tart cherry juice, which is thought to aid in muscle recovery.


I've seen this exact pair of coyotes three times now. I have a few blurry photos of them. They're about the size of my dog, who is roughly 60 pounds, so they are sizable and could hunt a small dog or child. However, they're very cautious around people still, and appear well fed. The wildlife in central park is highly adapted to the presence of people and stays away, except to dig through the park trash.


it's also true for people in cgs (centimeters, grams, seconds) sports like running, cycling, and lifting. if you look at the best in the world (pogacar, ingebrigtsen, blummenfelt) they don't look like fitness models. they look surprisingly normal. carrying "extra" body fat is helpful for training recovery, hormone levels, mood, and sleep. if the sport requires getting lean to hit a weight target for a specific event, athletes can do that, but they shouldn't stay ultra lean during the majority of their training.


For Grand Tour cycling stage races, the GC contenders typically start the race carrying a few extra kg (although still very thin). This helps a bit to avoid getting sick or fatigued during the early stages and they know they'll gradually lose the extra weight as the race progresses.


I recently spoke with someone in biotechnology who was doing a deep dive on "exercise pills". she told me that it would only be approved if it treated a specific disease, like muscular dystrophy, because the FDA views any potential negative side effect as too risky to approve for healthy people. Long term negative side effects are tolerable in Duchenne muscular dystrophy because those people are going to die without intervention. Once people with DMD show the safety profile it can be evaluated for more conditions.


what if positive feedback loops are on short timescales (1k years) and negative feedback loops are on geologic timescales (1 million years)? then for current human purposes the negative feedback loops may as well not exist.


I think this is unlikely because in this scenario we would see a geologic record of many gap up instant warmings and then a slow decline, which afaik is not the case.


What about the perturbation of the typical cycles by dumping lots of climate warming gasses into the atmosphere?

If nothing serious is done (as we are doing at present) and the warming becomes a runaway, it will progress until the causes have dissipated (e.g. we are no longer pumping GHG into the atmosphere and the natural sources of these have been exhausted or at least come into some kind of equilibrium.)

I'm too old to be able to witness that but I think our race as a whole is likely to do so.


I considered this for my pet's medical care. I did some things at a very expensive private equity owned bay area vet clinic, and other things at a much cheaper location quite a drive away. The bay area clinic wanted 4x as much for a relatively routine procedure. But they also had new and more advanced imaging equipment and monitoring equipment, and veterinary surgeons with fancier degrees and specializations.


probably a significant amount, otherwise private equity wouldn't be buying veterinary practices all around the nation. I know that the service I receive at a veterinary clinic I used to go to has become worse, a number of vets quit and were replaced with new younger ones, and the price increases have drastically outpaced inflation. all after the original partners sold to private equity.


I don’t really know what the answer should be. I somewhat arbitrarily chose a vet, found the group they are a Bart of, and looked up their accounts up to autumn 2022:

  Turnover 987 =
    Goods sold 96
  + services 776
  + ‘health club’ 113
I didn’t look into the health club thing. I think it’s a subscription and it probably includes regular checkups, vaccines, and maybe some other random things.

  Staff costs 442 (50% of turnover)
  Lease payments 37
  
  Profit 69.3 (~7% of turnover)
I’m not very good at reading financial statements and I didn’t try to dig through all the costs. There are things like buying new equipment as well as things needed for each operation. The group spent 118m on buying up other practices, but I don’t know how much leverage they had. If we take those numbers in a conservative “what if they were trying not to profit” scenario where they have no leverage, that’s 177 in “profit” out of 987 in income, or about $1800 if you assign it proportionally to a $10k skewer removal (or $700 if the acquisitions are counted as free).

I don’t know how those numbers look to you. To me, they don’t seem insane and I’m not sure the difference would matter much — I doubt the person unwilling to pay 10k would be willing to pay 8.2k. Also, I would guess that sort of surgery to be lower margin than routine things, though maybe competition drives it the other way.


Someone who has never thought about off roading or 4x4s may be very surprised that the dirt matters so much because they have never thought about it. So it sounds like an important topic to address for the audience of the New Yorker.


I would only buy an e-bike with a premium brand name motor and battery. Bosch, Panasonic, Yamaha, Shimano, Giant. The next thing I would look for is 2 or 4 piston hydraulic disc brakes from SRAM, Shimano, Hope, Magura, Tektro.

As long as the bike has those three things sorted it's probably safe. Note that these things don't come cheap, so any e-bike with these parts is likely to start at $3000.

For specific bikes I like Priority Current. They're a little vague on the exact parts used because they may swap them out based on availability, but they usually pick real parts instead of cheap replacements.


I have bikes with mechanical disk brakes and one with Magura hydraulics. I actually like the mechanicals a bit better. Although the Magura brakes have slightly more stopping power, they're also more finicky and require a trip to the bike shop if they leak or develop an air bubble. The mechanicals I can adjust myself.

For me the real key is disc brakes (whether mechanical or hydraulic). Rim brakes don't have enough stopping power for an e-bike.


Where do you park a $3k+ ebike in a city? Most places I've lived, a $3k bike parked on the street wouldn't last more than a couple of hours.


I have a $3k+ eBike and lock it in San Francisco. Not all places but many. I lock it with three locks. Main lock is a D/U lock Abus. Second lock is a "LITELOCK" for front wheel. Third one is the builtin cafe Lock. It is actually pretty quick to put them all on/off. Or at least I don't find it a burden compared to parking a car. All hex things have these security by obscurity hex locks in them. I also have a child seat on the back. Perhaps I've been lucky or perhaps the optics of three locks, and a child seat and often a helmet for a 4 year old dangling down turn off thieves.


Here in Tokyo, people park these bikes all the time and it's not a problem.


Yeah I'm at Tokyo Disneyland right now, and I've seen unattended handbags left on tables in the outdoor restaurant seating area. I can't imagine people doing that at a large attraction in any big city where I've lived (London, Beijing, Shanghai), or where I live now (San Francisco).

Japan is like a different world. At least to me as a tourist, it feels so organized, safe, culturally rich and stress-free.

I wonder what Japanese people think and feel when they visit San Francisco.


> I wonder what Japanese people think and feel when they visit San Francisco.

Well, what they think of Paris is well documented:

https://en.wikipedia.org/wiki/Paris_syndrome

> Paris syndrome (French: syndrome de Paris; Japanese: パリ症候群, romanized: Pari shōkōgun) is a sense of extreme disappointment exhibited by some individuals when visiting Paris, who feel that the city was not what they had expected. The condition is commonly viewed as a severe form of culture shock.

> The syndrome is characterized by a number of psychiatric symptoms such as acute delusional states, hallucinations, feelings of persecution (perceptions of being a victim of prejudice, aggression, hostility from others),[1] derealization, depersonalization, anxiety, as well as psychosomatic manifestations such as dizziness, tachycardia, sweating most notably, but also others, such as vomiting.[2]

> While the syndrome has been particularly noted among Japanese tourists, it has also affected other travelers or temporary residents from East and Southeast Asia, such as those from China, South Korea, and Singapore.

I’m sure SF is all that and worse, although expectations might not be as high.


Similar thing noticed when visiting Korea as US natives. My wife was in a group that all headed off to the restroom at a restaurant just after getting a table, with a couple of in-laws who live there leaving their purses on the table. My wife exclaimed that they were forgetting their purses, to which they replied that it was on purpose and how else would they make sure somebody doesn't get their table!?


inside my office bike storage room, and inside my apartment building basement. the even more expensive carbon road bike goes inside my apartment. the city bike can be locked up for short grocery runs and things like that, but it doesn't stay locked outside for very long.


Even though bosch engines are amazing their support service is execrable. I had an issue where there was a weird noise after 25km/h and even if there was an warranty they are taking months to fix it. First they said it's normal then send a recording of the sound etc.. Bought a 5k bike with a good engine to not have these kind of issues or if you have them then the repair should be in point.


You don't think my Radrunner with mechanical brakes is safe?


Its safe unless you are riding on very steep long hills. People rode heavy bikes touring before disc brakes existed and didn't die.


Subjectively, it feels as adequately braked as any of my acoustic bikes (including a mountain bike with dual 4-piston hydraulic brakes).


Can we start calling them analog bikes instead? As a guitar player, acoustic sounds very weird.


“Acoustic” is just silly, “analog” isn’t much better. I’d call them “mechanical”.


I don't like riding heavy bikes with mechanical brakes because they never stop as reliably as good hydraulics. The ultimate limit is always the tire grip on the road, but it's easier to control properly set up hydraulic disc brakes to hit grip limits and get shorter stopping distances. Particularly down a steep hill.


You can get up-rated caliper brakes with very good stopping power, and in fact that's what comes on my Gazelle ebike as standard.


depending on the failure type (shear, compression, tension) carbon fiber behaves differently. but when the fibers actually break it pops so quickly that it exceeds human perception.

real time view of tensile failure: https://youtu.be/gmMRPmEYWhU

high speed 10m fps view of tensile failure: https://youtu.be/OePpVwCvCZg

when compressed along an axis that's not properly reinforced by carbon fibers, it will just disintegrate: https://youtu.be/BaSXRoD2xaQ?t=61

another interesting example of rapid failure: https://youtu.be/DM6J-yw8yjA?t=226


The same guy that runs the channel as your last video actually did one on imploding objects under sea depth pressures: https://www.youtube.com/watch?v=WD7CfnQC5HQ


Note that their pressure gauge only goes up to 4500psi. The water pressure at the Titanic's location is around 6000psi.
