Landlords would totally try charging space aliens rent.




Starbucks of “we used our influence over the coffee industry to strong arm and threaten the fair trade foundation into massively watering down the ethics requirements for fair trade coffee” fame.


Meanwhile the US has more people dead from covid than literally any other country, even most countries combined. Certainly more people dead than China (again, despite having a much smaller population, and much lower urban population densities, which you’d think would mean an easier time preventing the spread of a virus).

Literally “better dead than red.”

Also, it’s a real bold claim that covid quarantine is equivalent to an actual prison.

I discussed this with you in Mastodon: I used to be against geoengineering due to the massive amount if unknown risks. But now that the climate crisis has gotten THIS bad, the risk benefit analysis has been pretty significantly shifted and geoengineering seems like a viable solution despite the unknowns. Certainly more viable than doing nothing.


Again, for a sub run by self-proclaimed anarchists, they’re being awfully authoritarian.




“Virtually no ability to predict our performance in China”



I know it’s a really interesting development and could go on to help many people. But I can’t stop thinking about this turning into the Borg.


Well, considering that communism didn’t do that, you’re gonna have to give the shirt back.

“They shouldn’t have had kids in our shooting range, duh!”


That’s indeed what they, the people that the masses need to be liberated ftom, want you to think.






Didn’t Nazi Germany claim to be the third Roman empire?

I’m more hoping that other people see this and realize the BS that’s in the marketing of this and similar “wellness” products. I hate medical disinformation and the distrust of actual medical professionals that has arisen lately (but a random for-profit company that says this random thing is a wonder drug is totally trustworthy, apparently). Also, it’s fun to complain about stuff!



Here’s the thing: blood in a healthy human is almost always at near full oxygen saturation, even when heavily exercising. IIRC something like 98% saturated pretty much at all times. Breathing faster and heart beating faster? That’s your body’s way of keeping your blood maximally oxygenated. You can test this easily with a $20 pulse oxymeter that you can find online or at the pharmacy. Put it on, run like hell, and watch how your blood oxygen doesn’t really drop. If it does, call your doctor because it’s very likely something’s wrong.

And if the blood leaving your lungs breathing regular air is already very near saturation, that means it doesn’t have the ability to pick up much more oxygen even if it’s available! You only absorb about a quarter of the available oxygen in regular air in a regular breath to begin with, adding more oxygen is pretty much useless and will just get exhaled! We specifically have re-breathers for diving and space suits because we can’t absorb all the oxygen in one breath, and you don’t want to waste any to exhalation when your supply is highly limited! The reason your muscles run anaerobically when exercising is the bottleneck in delivering oxygen from blood to muscles, not a bottleneck in gas absorption in the lungs because the oxygen concentration is too low!

Humans evolved with 20% oxygen in the air, that’s the optimal concentration for us and the most we can take advantage of! The only people this is useful for is people who have trouble absorbing oxygen, but those people should be getting recommendations from their doctor and not buying random “health” products. Or, maybe if you’re a dinosaur and you evolved under something like 60% air oxygen, which was actually why animals were so big back then. /rant


The scuba community affectionately calls similar miniature tanks “three breaths till death.” Because it’s so undersized that you will very quickly run out of air, often without realising it.
