Because it’s low voltage DC. Like ~5-24V DC. That “block” that inserts into the receptacle and the usb plugs into is actually a mini transformer. Which converts the 120V AC into whatever DC voltage it states on the side of the “block”

Finding out the exact date of conception is basically impossible and historically the date of birth or baptism was the basis for age in western countries. Expecting everyone to change the convention for something like this is just unrealistic.

We as a society have decided that the time you spend inside your mother does not count as your age, and that's why we celebrate Birth Days to mark the passing of each year.
We could get more medical or scientific and say that while you're inside the uterus, you're still developing as a human being and you're not formed 100%, so we decide that when you get out, it's because you're fully formed and ready to rock the world.
In Korea if i recall correctly they are 1 year older because they account for this time, but again, it's a decision as a society.

A few things.

1. The default voltage for USB-C is a measly 5V. Think half (okay 5/9) that of a 9V battery if you've ever licked one. It can go as high as 20V but the receiving device specifically needs to request that - even then, not necessarily fun to be shocked with but not particularly dangerous.

2. The USB-C connector delivers power through pins on the INSIDE of the connector, making it extremely difficult to make contact

3. A USB connector serves DC power, your wall outlet is AC.

So in order to implement it on wall plugs you'd need all wall outlets and devices (from power strips to computers to stoves to vibrators) to be swapped out with new versions that negotiate the proper voltage, convert to DC. And new connectors - which is harder to make in a non-exposed package if you need to support up to 120V.

Edit: mixed up AC/DC

> other times they perceive real differences in quality between name brands and store brands. So if people really want Ritz crackers and not an off-brand, they'll stop shopping at a place that doesn't sell Ritz.

Off-brand Cheez-its are trash. I will die on this hill.

Phone chargers already convey more than just electricity. Any 'smart charger' or similar will include some data exchange through the cable, so that the charger can actively change its voltage rates in a way that the phone's battery and programming can take advantage of.

The construction of a cable has enough room for a small chip to interact with what it plugs in to. If Apple wants to make their cords proprietary and not just the charger, then they can include a small chip that adds a small amount of data to the interaction. Then the programming of the phone can change how it takes advantage of the charger based on the existence (or lack) of this extra data.

A similar practice happens with ink and toner cartridges. Off brand cartridges can be rejected by a printer's programming, even though the only difference are the chips and wiring that interacts with the printer to tell it "on brand cartridge" or not.

In a USB plug the pins are tucked inside surrounded by ground, so they are not likely to get shorted by the plug falling onto a metal object. It would definitely damage the computer if they were. USB is low voltage, so it would never be dangerous to a person.

The outside shell of the connector is electrically neutral, the only points in the connector with a different voltage are inside the connector, and no properly designed device should ever supply power along a USB+c connector without verifying it can receive power

Wall plugs have two different exposed conductors an inch or so apart with a over a hundred volts AC between them

“How old you are at birth” varies depending on the culture. If you follow eg the long standing Korean method, I’m two years older than I am if you decide that age at birth is 0 months old. (South Korea is changing to the 0-at-birth scheme soon.)

Space-time is the medium of light. Light is neither a particle nor a wave but behaves like both, depending on the situation. The particle and wave models of electromagnetic radiation are useful in certain ways but are in no way a 100% what is happening in reality. We do not really fully undersatand how light is like this but it is probably related to quantum uncertainties. We do not fully understand space-time either.

McD's have some free coffee offers in some markets too, to try and incentivise people to come buy McBreakfast. That's probably more like what u/Educational_Sir3783 was thinking.

Because when people are willing to pay for brands. It's not always about paying for simply the logo. It's about what comes with the logo i.e. quality of the product that has been acquired through time.

For instance... I'd rather buy a certain brand of cheese/chips/ketchup than the generic store ones because that brand just tastes better. And it's worth the difference in price.

Also... Some people rather pay extra for the logo simply cause they want to be associated with the class status that comes with the product.

Damn polar bears... they bite you, you die... you bite them, you die

A LOT of reasons.

• Name brands often have sexier packaging, assembly, and presentation than not-name brands. A lot of people are into that, and pay the mark-up on the name brand.
• Name brands sometimes go on sale based on discounts from their manufacturer for lower prices than non-name brands. You can often score really decent deals on stuff like branded laundry detergent, shampoos, canned sauces, and so on. You just have to wait for the sale.
• Name brands are ADVERTISED. Want an example? "Aspirin" is "Acetylsalicylic Acid". Which do you think most people recognize? They'll buy Aspirin and Tylenol because they "know" what it is due to seeing the ads. But they won't buy ASA or Ibuprofen, even though they're the same thing.
• People are really gullible. Brands tell stories about their product that people believe, and so they buy them rather than no-brand stuff.
• Some name brands are simply better than no-name. I've never found wheat chaff in my brand flour, and I do a LOT of cooking. I have found wheat chaff, and had to sift it out, in the non-branded stuff. And most tomato sauce is far better when branded, trust me on this. (I make a ton of pasta).

All of these things make people go to your store and buy your store's stuff. A great, great many people would never go to your store if it only had non-branded stuff though.

Because 9 months is vaguely close to an average date from conception so you can't just backdate it from birth and have it mean anything. And many people don't know the precise date of conception.

Meanwhile, it's pretty unambiguous when you deliver a baby.
