    It's like living 35% longer, except that the extra time is at your prime instead of at the end! I get joy out of my hobbies and projects and would appreciate the extra 40 hours a week for them.

  2. AEDs don't restart hearts. A flatline rhythm, AKA asystole, is not a shockable rhythm. The AED will figure out if it's a shockable rhythm though, but it's important I ruin all medical shows and movies.

    AEDs are great if people know how to use them and know what else to do (check pulse, delegate someone to call 911), run chest compressions while someone else attaches pads, etc...

    You should take a class though, because you don't want to have to figure everything out for the first time during an emergency. You get hands on experience with a trainer and mannequins and learn to handle and recognize some other emergency situations.

    You'd be surprised. Being asked if things are more significant than normal or other similar questions can make you wonder because you don't normally think about the world that way.

    There have been some interesting studies on the LSD placebos:

    Salvinorin A is only comparable to LSD in potency, not duration or effects (unless you think any type of feeling weird or changes in perception are equivalent)

    LSD does not cause a flattening of affect, quite the opposite actually.

  6. LSD is not a KORN, its effects are largely mediated by the serotonin 5HT2A receptor (blocking that receptor with ketanserin stops effects). I'm not sure why 'increased insight' is your example of a negative side effect anyway.

    The non-placebo group got an imperceptible dose, not a 10-strip. That's in the summary. You tell them they can't drive, to have someone ready to pick them up, you get a medical history and screen for mental illness. The test was conducted by having them reproduce a time period by holding a space bar, not by asking if they knew what time it was or how long had passed. That's in the summary. Psilocybin is the best drug for smoking cessation by a large margin ( https://www.hopkinsmedicine.or... ). LSD may have the same promise. You may find that silly, but that could save tens of thousands of lives in the US every year. 70% of smokers want to quit: https://www.cdc.gov/tobacco/da... 480,000 people die per year from smoking https://www.cdc.gov/tobacco/da... If all 70% that wanted to quit took psilocybin we'd be talking about over 200k lives saved per year. And that's not the only thing psychedelics can be used to treat!

    Just because a file is not executable does not mean that it is not sensitive.

    Replacing unauthenticated data takes different skills from owning a server and leave very different traces. Rooting a box can leave behind evidence and is higher risk than replacing unauthenticated traffic.

    Plus, it doesn't take a global active adversary to replace http traffic, it just takes a WiFi pineapple and an afternoon of sitting in a coffee shop fiddling to do the former attack.

    Downloading executable files, downloading risky file extensions (doc, pdf), and downloading any document where integrity matters means that http is a risk. If someone downloads some old games from an HTTP archive, malware could be added. If someone downloads some PDFs with an outdated reader, there could be malware. If someone downloads some forms they're going to fill out later, changing the location they're supposed to be emailed/faxed/whatever means someone could give out PII or financial information. If someone is reading old news stories, changing the content of those stories to suit an attackers narrative could be very valuable. Just because the author can't imagine the security implications, doesn't mean organized crime, bored hackers, or nation state actors aren't thinking about it.
