Consider what your body is adapted to over millions of years of evolutionary history. Go back in time ten thousand years, a blip in that history but to a lifestyle that is reflective of the other millions of years.

Your ancestors spent lots of time outside, did physical activity all day, ate whole unprocessed food, didn’t have screens and cars and light switches, and didn’t sit down for huge periods of time.

Science is finding that as we deviate from those things we develop illness, our bodies don’t handle it well. Your body needs to move a lot to work properly, sitting or lying down all day is not what it is adapted to and its systems break down. Blood doesn’t flow properly, raising clot risk. Bones soften, muscles atrophy, postural issues develop, important hormones get out of whack, risks of metabolic syndrome increase, heck even sexual function deteriorates.

Thing is, people are adapted to an environment where we HAD to be active and work a lot, and we have an instinct to minimize energy expenditure within the framework to conserve calories. If the natural situation where a lot of work is inevitable is gone, turns out we can often be pretty lazy and not move much at all. Fighting that instinct is super hard.

In third world countries, It's totally common that a person who has no money publish in the news that he/she has a kidney for sale. It's totally legal.They get the money and then go to the hospital and say they are volunteer to give the kidney to the person they got money from.

  1. Flopping happens in every sport where physical contact could be a foul

  2. It happens a lot in soccer relative to other sports because if players do not fall down and continue the play, the ref may decide to “play advantage” ie let them continue and not whistle the play dead. Often times this is less advantageous than the free kick so the player goes to ground to get the ref to whistle.

I'll add a little bit of philosophy and theory to this:

The general trend in the development of paradigms, rules and methodologies has been to restrict the programmer from doing certain things. goto lets you arbitrarily move to a different place in the code. This can be made less arbitrary by forcing the programmers to use functions and loops.

Similarly, encapsulating variables is a restriction. It restricts easy access to the variables from outside the class.

Type safety is a restriction. It forces assignment and other operators to require explicit casting for variables of different types.

So on, so on.

Without restrictions, the programmer could do anything at any time and it would be extremely difficult to read such code. When you restrict things, you force the code from different programmers to be more easily understandable and you (hopefully) decrease the amount of bugs in the code.

Sometimes you create a restriction that makes it hard to express some things in a clean way. For example, in C, goto still has a place in error checks and in ensuring that an error causes a function to release the resources it initialized at the start of the function. In more modern languages, there really isn't any reason to ever use goto, since the languages offer other more powerful (and more restricted!) constructs for dealing with the issues that goto is used for in C.

This have evolved over time. Football players do struggle with life changing injuries in bad tackles. Since it is a game played primarily with ones feet a bad tackle may cause horrible leg injuries, smashed knees, etc. And there is little protective gear that works without hindering the players performance. So in order to reduce injuries there is a very strict no-contact policy that is enforced very harshly. This is to ensure that players pull out of potentially risky situations. The problem with this is that it is very hard for the referee to judge if there were contact or not and how hard the contact was. One of the few things they can look for is how injured the player is. If they are rolling around in pain it was probably some hard contact. But this is of course open to abuse. Players can fake injuries to get other players penalized. This is of course not allowed either but it is hard for the referee to judge these things. And when they need to enforce the no-contact rules in order to prevent injuries they do more often judge in the favor of the seemingly injured player.

People are working on reducing this issue though. It is possible to use camera replays to catch things the referee did not see. This does however take time and either slow down the game or is only available after the situation have been resolved. The cameras might not even catch the incident well, if the match even have a full complement of TV cameras. But it can help to give referees some advance notice for the next match. Or the players might get penalties between matches.

Because the data is compressed to reduce download time, and inflated at the host computer.

Imagine that you live somewhere that for every sentence, they they make you append "I love our great and mighty country and our wonderful leader."

If you had to dictate your work over the telephone, you'd probably abbreviate the repetitive part to "I love the country, etcetra."

Then when the secretary typed it, she would expand the crazy stuff herself.

Everything except purely random data can be compressed, almost always at least 50%. Windows expanded from 11G to 65G, so it was compressed to 1/6 he size.

Text can usually be compressed to 1/15 the size. One reason is that all the spaces can be replaced with a very short symbol (string of bits). Rare letters like Q and Z are replaced with a long string of bits.

The minimum requirements for windows OS are far bigger than they realistically need to be, because at some point in the past someone took Microsoft at their word. Installed it on a drive that was near the absolute minimum and then a few years later didn't have enough space left to install an update.

So nowadays MS likes to err on the side of caution. And figure what people actually need to run the OS, plus typical minimal applications disk requirements, plus swap file, plus space for updates and logs plus a healthy margin just in case.

You can try to get away with much less than what Ms says is minimum requirements. You probably shouldn't.

With hard drive space for consumer computer being nearly dirt cheap and for servers being mostly virtual and adjustable, this really shouldn't be an issue in most cases anyway.

Because it's beneficial for them and their team.

  1. It alerts the referee to even the slightest touch that could be deemed a foul and sometimes even fools the ref into believing there is a foul when there was no contact. So this increases the chances of the team getting a free kick or a penalty

  2. There's rarely any consequences for flopping or faking injury. Proving someone is not hurt is difficult and the player often waits for the team doctor to come on the pitch to asses their "injury" which makes it more believable and harder to conclude that they're entirely faking

  3. A tackle causing an injury might mean that the referee feels like they should give a yellow or red card to the offending player.

In summary, they do it because even though it looks silly, the potential benefits massively outweigh the possible negative consequences.

I'm not saying this is right but this is just how football works these days

Windows is pretty bad at cleaning up after itself. Even if installation size does not equal download size as ikantolol said just compare Windows size after install and after 2 years of use. My Windows folder started out at around 9GB and I'm now at 26GB. And after all you need headroom for updates and other applications.

And in case of SSD it's pretty bad for its health if its constantly full or nearly full as it can't wear balance as well.

But Microsoft has a tendency for strange requirements. Just look what they recommend to run exchange, it's crazy.

Electricity flows in a loop - a complete circuit back to the power source. With a battery, yiu have to have a wire going to both ends of the battery to complete the loop.

Water conducts electricity, so it acts a bit like a wire. Electricity will always take every possible path to complete its loop. Electrical wires are designed with insulating covers (plastic) over the surface of the metal specifically to keep the electricity only in the wires. But in water the electricity can spread out.

Now imagine that if you put a bare metal wire in water. The electricity will try to flow through the water on all directions to find the loop that completes the circuit.

Often the loop is quite vague - especially in mains power. The power plant produces power, and normally the loop is two separate wires on your electrical cables. However, there are other loops possible - the electricity can go through a pipe into the ground, the through the ground back to the power plant and the back into the generator through a ground wire.

So if you drop a hair dryer on the bath, bare wires inside the hair dryer get exposed to water. The water spreads out through the water looking for a loop. It finds the drain pipe which goes into the ground and that gives it a path back to the power plant.

Now you reach in to the bath to pick up the hair dryer. You have one hand on the metal bath tap and yih reach in with the other. Your body conducts electricity and when you reach in, the electricity finds a new loop from the water-through your arm, then body, then down into the tap, then into the water pipes. So, some of the electricity flows through you and that is why you get shocked.
