A Japanese immunologist spent 20 years proving that the chemicals trees release into the air walk into your bloodstream, hunt down your stress hormones, and arm your immune system in ways no therapist or pharmaceutical has ever matched, and most of the data has been sitting in Japanese medical journals for two decades waiting to be translated.

His name is Qing Li.

He is a clinical professor at Nippon Medical School in Tokyo and the president of the Japanese Society of Forest Medicine. The Japanese government has been funding his research since 2004, and the body of work he has produced is the reason forest bathing is now an officially prescribed clinical therapy in Japan and Korea.

The story actually starts in 1982, when the Japanese Ministry of Agriculture, Forestry and Fisheries coined the term shinrin-yoku to describe the practice of slow, mindful walking in a forest. They did it for a practical reason.

Japan was urbanizing fast, stress-related illness was climbing, and the country had thousands of square kilometers of forest sitting unused. The idea was to give people a reason to walk into the trees... They had no idea what was actually happening to the human body during those walks until Qing Li ran the first proper experiment in 2005.

He took twelve healthy adult men on a three-day, two-night trip to a forest park. They walked for a few hours each day. Nothing strenuous. No prescribed routes or breathing exercises. They simply walked slowly through the trees, breathing the air, looking at the forest.

Li drew blood and urine samples before the trip, on the second day, on the third day, on day seven after returning home, and again on day thirty.

The numbers that came back from the lab were not what anyone expected.

The activity of a specific type of immune cell called the natural killer cell, which is the cell your body uses to hunt down cancer cells and virus-infected cells before they can spread, had jumped by roughly 50 percent during the forest trip. The actual number of natural killer cells circulating in the bloodstream had increased significantly.

Three different anti-cancer proteins that those cells produce, called perforin, granzymes, and granulysin, had all risen sharply. And the effect did not disappear when the men went home. The immune boost was still measurable on day seven and was still partially present on day thirty.

Two hours a day in a forest had upgraded the immune system for a full month.

Li ran the same experiment with women a year later and found nearly identical results. Then he ran it with a control group who took a three-day trip through an urban area with the same amount of walking, the same hotel quality, and the same diet.

The urban group showed no measurable change in natural killer cell activity at all. The forest was doing the work, not the vacation.

The mechanism turned out to be a class of airborne molecules called phytoncides. Trees produce these compounds to defend themselves against insects, bacteria, and fungi. Pine, cedar, oak, and cypress trees release them in particularly large amounts, especially in warmer weather and after rainfall.

When you walk through a forest, you are inhaling those molecules into your lungs and absorbing them through your skin, and once inside your body they appear to directly stimulate the production and activity of the very immune cells Li was measuring in his lab.

Roughly 50 percent of the health benefit of a forest walk, according to Li's data, comes from the chemistry of the air itself. The other half comes from what the forest is doing to your nervous system.

This is where it stops being only about the immune system and starts being about stress.

A separate Japanese research team measured cortisol, the body's main stress hormone, in 84 participants across 35 different forest sites. They drew samples before and after a 30-minute walk in each forest and compared them to control walks in matched urban environments. The cortisol levels of the people who walked in the forest were lower than the cortisol levels of the people who walked in the city by a significant margin. Their heart rates were lower. Their blood pressure was lower.

The activity of their parasympathetic nervous system, which is the part responsible for rest and recovery, had gone up. The activity of their sympathetic nervous system, which is the part that drives fight or flight, had gone down.

Then a researcher at the University of Michigan named MaryCarol Hunter ran the cleanest version of this experiment ever done. She recruited participants from a city and told them to take a nature pill three times a week for eight weeks.

They were free to choose the time, the place, and the duration of the nature experience, as long as it was outside, in daylight, and free of phones, conversations, and aerobic exercise. They sent her saliva samples before and after each session so she could measure cortisol changes accurately and rule out the normal daily drop in stress hormones that happens to everyone.

The result was that participants experienced a 21.3 percent drop in cortisol per hour spent in nature, with the biggest payoff happening between minutes 20 and 30 of the walk.

After that, the cortisol kept dropping, but more slowly. The threshold dose for measurable stress relief was just 20 minutes outside in something that looked and felt like nature.

What none of this means is that nature is a substitute for therapy or for medication when someone genuinely needs them. Therapy treats different things than a walk does, and Li himself has been careful in interviews to call forest bathing a complementary intervention rather than a replacement for clinical care.

But what the research has settled is that the human body has a physiological response to being among trees that operates on the same biological systems modern medicine is trying to reach with drugs and clinical protocols, and that response is fast, measurable, and free.

The strangest part of Li's work is the implication he keeps repeating in interviews. The average person now spends more than 90 percent of their life indoors. Their cortisol stays elevated. Their natural killer cells stay sluggish.

Their parasympathetic nervous system rarely gets a chance to take over. The system that was tuned by millions of years of life under a canopy of trees is being asked to run permanently inside a box made of drywall and screens.

Your body has not forgotten what it is supposed to do in a forest. It is waiting for you to walk into one.

[Devon Eriksen @Devon_Eriksen_]

Okay, time to explain the Imperial system, the metric system, and why attempts to replace either with the other are all retarded.

They have two different purposes.

The metric system is designed around precise measurement of objects. Its goal is to make engineering and scientific calculations simple.

The Imperial system is designed around humans. Its goal is to make calculation unnecessary.

100 degrees is really hot. 0 degrees is really cold. Anything that starts with a 5 is cool, anything that starts with an 8 is warm. No computation.

6 feet is tall, 5 feet is short.

100 pounds is light, 200 pounds is substantial, 300 pounds is heavy.

A 1000 square foot house is small, a 2000 square foot house is medium, a 3000 square foot house is large.

1 mile is a short walk, 2 miles is a medium walk, after that it takes a while.

1 acre of land is a homestead, 10 acres is an estate, 100 acres and up is a ranch or a farm.

Do you see now why it is so strange and awkward to convert from miles to feet?

It's because converting from miles to feet is not something you're supposed to do in the first place. Yes, they are both measures of length, so they are technically convertible, and yes, on rare occasions, you might need to do that.

But feet are for measuring humans, and things built around humans, like doorways, and mattresses. Miles are for measuring travel distance.

You wouldn't measure the distance between Seattle and Portland in feet for the same reason you wouldn't measure the distance between Tokyo and Osaka in mattress-lengths.

It would be silly.

This is why Americans so fiercely resistant to any notion of "conversion" to the metric system. Because it makes no sense. We already use the metric system for what it's good for, which is doing physics and chemistry and whatnot.

But converting everyday measurements to the metric system would be less useful, generally inconvenient, and serve no purpose other than to make petty government bureaucrats happy that everything is now tidy, orderly, and worse, three qualities that bureaucrats love.

I thought about this carefully when I wrote my first science fiction novel. In the world of the 22nd century, extraterrestrial settlers ("Orbitals") use three systems of measurement.

They measure themselves in feet, inches, and pounds.

They measure the spacecraft and habitats they build in meters and centimeters, grams and kilograms.

And they measure space travel distances in light-seconds and light-minutes.

Each system has its own natural scale.

The sole exception to this is when Marcus doses himself with drugs for high-g resistance, Miranda objects that he has taken too much, and Marcus responds by stating his mass... in kilograms.

Why?

Because they're talking about drug doses, a engineering measurement. Drugs are dosed in milligrams per kilogram.

So, yes, the Imperial system makes perfect sense when you understand what it's for, and no, we ain't changing.

And, as a general rule, when an entire civilization of smart people does something for centuries, and it makes no sense to you, they're probably not being silly.

It's more likely there's something you don't know.

Space radiators are not sci-fi. The ISS already uses this physics. SpaceX is just scaling it with Starship

People act like cooling a data center in space is some impossible sci-fi problem. It is not. The physics is simple:

On Earth, heat can leave through air, water, fans, cooling towers, and convection. You cannot “blow” heat away in space the traditional way

Instead, you have to move the heat from the chips into a liquid loop, pump it into radiator panels, and then radiate that heat into the vacuum of space as infrared energy

That is literally how spacecraft cooling works:
Heat in → liquid loop → radiator → infrared radiation into space

The equation is basic physics:
Power Radiated = Emissivity × Area × Stefan-Boltzmann constant × Temperature⁴

If you want to cool more compute, you need more radiator area, better materials, higher operating temperatures, better liquid loops, and more power. This is exactly why the new SpaceX AI1 data center satellite features massive deployable liquid radiators

The hard part is not inventing new physics. The hard part is scaling the system. And that is exactly what Starship is built for

The ISS already uses pumped coolant loops and huge external radiators to dump heat into space. SpaceX is not proposing magic. It is taking a cooling method already proven in orbit and scaling it with Starship, mass production, solar arrays, and orbital infrastructure

A data center in space is not a building flying around Earth. It is compute, power, radiators, and communications engineered into a satellite

Proven space physics, scaled by SpaceX 🛰️

This would be the start of a science fiction movie in a saner, safer world. In our world, it’s simply another puzzling reality ignored by most.

[U.S. National Intelligence @ODNIgov]

The existence, history, locations and funding of these U.S. funded biolabs was intentionally covered up by powerful people falsely claiming that the labs do not exist and accusing anyone who says otherwise to be foreign assets and traitors to America.

Those lies are still being propagated today by the same powerful people and their allies who wish to see this dangerous research continue with little to no oversight.

[Jeffrey A Tucker @jeffreytucker]

The revelations six years later are pouring out so quickly that it is impossible to keep up much less mentally process all this:

* The Director of National Intelligence has documented 120 US-funded/owned biolabs in 30 countries many of which are manufacturing and manipulating infectious diseases.

* Senator Rand Paul's committee has released the receipts concerning US funding/backing of the manufactured SARS-CoV-2 virus/vaccine as part of this program.

* Senator Johnson has produced definitive evidence that US public health agencies knew of the grave dangers of the shot to everyone but said nothing.

* Many officials are privately admitting/proving that the whole point of lockdowns was to preserve population immunity for the shot and block other avenues toward wellness.

* Hardly any of this makes the national news and one wonders if the public mind has any awareness at all.
