When I was an EMT we got a call for a house that smelled really bad. This was in the country so the houses were far apart and the neighbors called it in. When we arrived in the ambulance we could smell it inside the ambulance as soon as we turned into the driveway. I remember because we had just picked up lunch and I was eating fried chicken. The smell was so bad I couldn’t eat fried chicken for years without thinking about it. The man lived alone and had no family and no one to check on him. He died watching TV and was still sitting in his recliner. He’s body had decomposed enough that his head sank down into his chest cavity. It was the most awful thing I ever smelled. The coroner later told us he had died around 6 months ago. In all my years I’ve never seen a naturally mummified body. The humidity in southern Louisiana is too high to allow it to happen naturally.

It's important to note that ChatGPT doesn't "understand" things in the same way we do, and doesn't "think". So it does tends to get a lot of stuff wrong.

That being said, it's quite a good bit better than previous attempts at similar things.

Yeah "water purity" is a grey zone, lots of scams. When I was young I earned some cash as a handyman. The stuff some people wanted me to install in their water system was baffling. Especially since I live in an european country with probably the best tap water quality in the world.

edit: just watched the vid, hillarious, they are just disolving the toxic metal particles in the water holy moly and use distilled non conductive water for the "proof". Yay humanity!

Electricity is so bad at killing microorganisms in small amounts that in lab sciences we actually use it to introduce new DNA into them through a process called Electroporation. Basically, you send electricity into a solution that contains your microorganism and the new DNA you want it to have, and you zap the solution to cause pores to form in its cell membrane. These holes are big enough to allow the DNA to enter. It’s a very useful technique.

There are all these videos (I'll try and edit one in if I find it) of Chinese "water boilers", which are just + and - electrodes that you put into water. The problem is, even in "clean" water, the electrodes themselves begin to electrolyze into the water. The tap water isn't clean either, so all the minerals begin electrolyzing and depositing onto the cathode as well.

EDIT: This is used in a scam to show that one's water is actually impure, and that one should buy the salesman's water filter. https://www.youtube.com/watch?v=ASnLL6ebaco

This is not ELI5 but.....Ozone is produced when oxygen (O2) molecules are dissociated by an energy source into oxygen atoms and subsequently collide with an oxygen molecule to form an unstable gas, ozone (O3), which is used to disinfect wastewater. Most wastewater treatment plants generate ozone by imposing a high voltage alternating current (6 to 20 kilovolts) across a dielectric discharge gap that contains an oxygen-bearing gas. Ozone is generated onsite because it is unstable and decomposes to elemental oxygen in a short amount of time after generation. Ozone is also commonly used to disinfect bottled drinking water, as it is both soluble and effective at killing microorganisms via the oxidisation of their cell membranes. (So you're not that far off....)

I can't refrain from not denying that it isn't not, because it maybe would or maybe would not directly break the subreddit rules. But I would say that I could not resist the irony. And if it saves me from being banned, I must say that I did type all the comment, and that 1/3 of the paragraphs are mine.

We don’t pay to live. We work to live and so does every other animal. A lion hunts for food. A Beaver builds it’s dam for shelter.

Humans have figured out that if you specialize in a single activity, and do it better than anyone else, people will trade you for that skill.

For instance one person is a really good house builder and another can grow more food on a plot of land than anyone else. They trade building a house for food or vice versa.

At some point we invented money to represent the value of our work. So now we don’t have to build a house for someone that doesn’t need it but just pay them with dollars. This makes everyone’s value more easily transferable. You don’t need to find someone with excess of what you need and just happens to need the thing your providing.

Even without money, you would be hunting, gathering and building in a state of nature. Money and or paying just makes things easier.

Money is just an abstracted token of your labor that you trade for goods or labor that you are otherwise not able to get/do for yourself.

It would cost you nothing to wander onto public land and subsist for yourself. But if you are not specialized at it, then you are going to be fighting tooth and nail just to exist.

There are a lot of reasons, if we can separate them generally into two categories:

  1. What the actual fat does to the body
  2. How people become obese

For the first - The hormones released by fat can cause many problems, the fat itself can literally squeeze and crush the internal organs (that is what happens with OSA), the weight ruins your joints, etc..

The second - No one becomes morbidly obese by eating carrots and apples. You need to consistently be eating really shit food for a long time in high quantities to become truly obese (theoretically it is just calories in and out but realistically you can’t actually overeat on cabbage). These types of foods have a great impact on hormones, your blood vessels, your gut microbiome, and so many other factors that basically negatively impact almost every system in your body. This paired with being less mobile (also due to step one) can have a dramatic impact on your cardiovascular system.

To really explain everything would take literally hours, but basically these two categories are responsible.
