any water hot enough to kill germs would burn the gently caress out of your gums pretty sure we take hot showers not because it's necessarily any cleaner but because it just feels way nicer. cold showers suck! but they still get you clean

This causes radio freq radiation and yeah if things are poorly shielded it can cause weird hiccups. My wild guess is the control board of your audio system is poorly shielded and it gets briefly screwed with by the motor overshoot, which causes it to reset, which causes your computer to forget what kind of audio system was connected. I had a USB-C hub that would only work properly if it was covered in foil. Just so much crazy interference from that lovely device.

If all other traits are the same, they could convince themselves that any two people were twins. They also described mistaking a known twin and an unrelated friend with similar hair to be the twin and her sister. If two twins are pointed out to them, they can piece together that they do look more alike than the other indistinguishable faces in a crowd. Thanks so much for this! I've been reading an Oliver Sacks book--he had face blindness, and also studied a lot of crazy brain stuff throughout his career. I can't really wrap my head around prosopagnosia but I think an even worse problem is recognizing faces just fine, but having a deficit in the part of the brain that knows whether something is familiar. This is what leads some people to be convinced their friends/family have been replaced by imposters.

Isn't it the soap though that would loosen the oil and grime allowing the water to wash it away off your hands? Water temp is meaningless because it's soap that does all the work in effectively cleaning your hands.

Helith posted:Isn't it the soap though that would loosen the oil and grime allowing the water to wash it away off your hands? Soap is definitely the most important factor, but anyone who's ever had to wash off a bunch of grimey machine grease knows that warm water makes the process go much faster. Or if you haven't experienced that, maybe you've tried washing a butter dish with hot vs cold water. Those are very visible, obvious cases of oily mess. But on a more subtle level, a lot of germs are harbored by oily dirt, and kept from dessication and death by that protective oily layer. So to really wash well, washing grime off is really important. Warmth helps. But again soap is the most important part for sure. You can wash it all with soap and any water, it just might take more time and scrubbing if the water is cold. My point is the study that claims that water temp doesn't matter is based on washing off germs like what you'd pick up from a subway pole or whatever, not for getting actually dirty. If you have warm water you might as well take the advantage, plus it feels nicer.

If I use my phone as a USB tethered hotspot connected to my PC, and then enable my VPN on said PC, is my traffic hidden or does USB tethering gently caress with that? My PC doesn't have a wifi adapter and I've not got access to ethernet ports, so I just use my phone to connect to the internet.

My PC doesn't have a wifi adapter and I've not got access to ethernet ports, so I just use my phone to connect to the internet. A VPN will make an end-to-end encrypted tunnel, so any devices lying between your PC and the VPN server will see nothing but scrambled bits. Doesn't matter if the connection is your phone's data plan via a USB connection, a residential cable/DSL/fiber hookup via ethernet or wifi, an ancient dialup modem, or anything else.

All the tools on the IRS site (get my payment) do not indicate anything at all. They're at a complete loss and as far as helping them, I am too. If anyone could help with what to do next, it would allay the worry of a kind older couple.

How come certain foods are safe to leave out at room temperature for extended periods (bread, cakes, muffins, etc), but others have strict guidelines to be refrigerated ASAP? I'm currently doing quarantine in a hotel and sometimes they leave food for me but I'm asleep and don't bring it in until a solid 4-5 hours have passed. It makes me feel apprehensive eating it as I don't want to get sick (they're usually chicken dishes). I never used to be strict with food safety (I'd regularly leave cooked food like stew, lentils and rice out overnight and happily eat it the next day with no problems) but no longer do this.

The stuff that bread and cakes are made out of isn't the same as the stuff that chicken is made of. There's essentially no bacteria present in a bag of flour or sugar or whatever, and even if there's a bit of bacteria on the egg shells from the eggs used to cook it those will die pretty quickly and cleanly just as a requisite of the bread being finished. The main way those things go bad is by getting moldy, which takes longer than bacteria. 4-5 hours isn't really a huge deal honestly, there's a billion people across the world that throw their lunch in a bag at 7 AM to bring to work and eat at noon every day of their lives and never get sick.

It has to do with how quickly microorganisms can start consuming the food and turning them into things that make you sick. Bread is dry and starchy and tough for bacteria to attack. It falls to fungus, and that can take weeks to set in. You may notice that flour lasts forever in the pantry if it stays dry and insects and large animals don’t get to it. Cakes and muffins are similar. High sugar content can also have a preservative effect. Sugar is hygroscopic, it absorbs water. A bag of sugar lasts as well as a bag of flour. Bacteria would love to eat it, but if it’s not dripping wet, osmosis carries water to the sugar right through the batcteria’s cell membrane, killing them or at least causing them to go dormant. Honey is edible for millennia because as wet as it seems, it’s not as wet as the inside of a cell and it still has that drying effect. If the food item is warm and wet, with fat and proteins and modest sugar content, that’s the perfect opportunity for the dangerous bacteria to chow down.

alnilam posted:I always found it interesting that fish gets dangerous so quickly. What's so different about fish that makes it go bad in like an hour vs most land-based meats? Food poisoning from fish can get really bad, like, lifetime consequences bad. Ciguatera poisoning (infection? contamination?) is caused by a microscopic algae that can mess you up for years. Cooking will destroy almost all of it, but not all of it, and once fish starts to go off it can multiply to the point where your system gets overwhelmed by it. Or if it didn't get cooked properly, eating it straight out of the oven can make you sick as well. Compare that to beef where if it's been prepared properly, you can basically eat it raw. I think that's because they're a ruminant, and destroy parasites and bacteria they get into their systems with the whole 4 stomach set-up. edit: that's interesting about the temperature difference, I wonder if there's a difference between tropical fish and coldwater fish.

Some of the other pages talked about that. The answer is yes. A refrigerator puts tropical fish enzymes and bacteria farther out of their normal operating zone, and they last longer than temperate fish.

I remember a game at Dave & Busters in the mid 00s that I can't remember the name of, and I can't think of unique enough search terms to search for it. It was a shooter that sat (I think) 4 people and was maybe 2 or 3 stories tall. Each seat was on a vertical rail, and you'd get taken up or down based on what you were doing. I think you were shooting balloons, some of which had arrows that would send you up or down. Does anyone remember this, or can puzzle out a search query.

I do remember playing it at a Sega Gameworks location in the late 90s or early 2000s, so the game is at least that old and you might have luck spotting it in gameworks footage. I've tried googling for it and can't locate the game.

Why can't we cook and eat rotten food? The danger is bacteria, virus', parasites and what have you that colonise the rotted food. Sufficient temperature denaturates the proteins and kills all the nasty little bugs in the food. So, what is it additionally about rotten food that makes in dangerous, even though all the mirco organisms can be killed?
