Correction: Summer Yue deletes Summer Yue's emails. We don't say "Russian roulette shoots man."

I should heavily qualify this by saying that I don't think the study (which I have no access to) measured it this precisely or specifically. I think it was just people reporting roughly how many "cups" per day they drank over 40+ years. I guess I just get annoyed when I see "cups" as a unit of coffee science/health.

Translating from normie, sounds like 30-50g of beans, assuming a "cup" is 8 floz. and the water:coffee ratio is 15:1. Assuming Arabica, that's 450-750mg of caffeine.

And if you just add them to your spam filter, it won't even work easily, because they deliberately shift around the domains and subdomains they send from every so often.

I'm not knowledgeable enough to confidently verify this from the linked material, but aren't they keeping CO2 levels the same during the hypoxic periods? i.e. isn't this significantly different than just holding your breath/being choked/sleep apnea?

There is no downvote. There is only flag, and people are hesitant to use it, if it's even available to them in the first place.

Funnily enough, just a few weeks before that, REM released their eponymous album. Perhaps Morris was inspired by that?

Yeah, it was just a creative example of the type of awful AI responses search engines, including Google, give. It tends to contradict what you say, push everything towards useless and inoffensive "there are many complicated factors" analysis, and even contradict itself.

search: "coffee is mostly water"

"No, coffee is not mostly water. That appears to be a misconception based on a popular television show. Coffee is actually about 98% water."

They had to wait for additional characters to make a good guess as to whether it was Z or SE. So they thought that having your fingers already positioned close to both outcomes would allow you to handle that delay better. Maybe it allowed you to catch back up faster, or made it easier to handle both of those threads in your brain and nerves? Perhaps whatever letters came after Z/SE were unlikely to also be Z/SE, so it made it more likely your right hand would be typing the next character?

Selling individual rolls used to be more common. I'm sure you'll still see it today in smaller stores without a dedicated aisle for toilet paper/towels.

Why would they package those in larger packs? My guess is that the paper does help protect the roll while it's waiting to be racked. Dust/splashes/unravellng/etc. Might be where hotels get their TP.

While this can be mitigated somewhat by keeping backups on hand, the card helps because it gives you a convenient record of needing to restock, which you can just drop somewhere you know it will be used. Even in personal life that might be a good idea. Dropping an empty box of pasta or dental floss on the ground also serves as a convenient reminder, but it's harder to do with a can of tuna.

I had one of those 3D-only cards on my first computer. I didn't know about the passthrough and got pretty annoyed that my games sucked and never worked with the hardware 3D stack. I don't know if they didn't document it correctly, or if I just missed it. But when some support person finally told me, I was so pumped. I spent a while manually moving the cable to the 3D card when playing a game, until I finally got a passthrough cable.
