Doctors can keep people alive in comas for decades, we've got plenty of proof for that.

If your goal is to be "alive", then sure, it can be done using supplements and your body fat reserves - we've also seen a few cases of this.

The amount of permanent damage you do to your organs and brain, however, is unknown. How the extreme starvation feelings will rewire your brain is unknown. How your body will react when you start eating again is largely unknown.

Unknown is scary for doctors, they avoid anything and everything that isn't in their handbooks - for good reason! People sue people on a whim.

There could be a reason for such a structure. Financial institutions often still have very old esoteric hardware, such as mainframes. (Even if not actively used, they still need to keep it functional to access archived data.)

Just, because you can program and compile something without errors, doesn't mean it will run correctly.
Nested functions, calling a function within a function, which calls a function, etc... is a very common way of doing things.
However, some CPUs have a limit on how deep such a stack can go, going as low as to only 4 or 8 stacks deep. (Ex: Arduino.)
Very old hardware doesn't even have such a stacking possibility that allows nested functions.

The food and drinks don’t “NEED” the dyes.

There are certain foods that we know should look a certain way. And food scientists have spent a lot of effort determining what people think is appetizing. So as foods are more and more enhanced through GMOs, or high fructose corn syrup, etc. they know the color has to stay the same.

Colas for example had that brown color from caramel syrup, or sugars cooked down until they browned. Now high fructose corn syrup is used as the sweetener and coloring is used to restore the hue.

Why some food colors are harmful is a whole other concern. Sometimes a product has unintended side effects. We see that in medicines all the time.

I would not use the word "need." We don't "need" the drinks to begin with, which is the crux of why they have dye in them. Several things, pretty colors of the right type make people like things more. Red and yellow colors make you hungry. Blue colors make you calmer and more serene. The artificial colors are there to make the products more appealing. We have found that some dyes do seem to be corollated with health issues, and the ones that appear to have a causal link have been removed and outlawed. There is a little more to unpack. Corrolated does not necessarily mean causal. For example, it is true that regular drinkers of diet sodas suffer heart attacks at a statistically significant higher rate than people that just chug regular, sugary soda, but the corrolation is not causal. The reason for the corrolation is that more heavy people drink diet sodas. The risk factors are already there. The diet soda is just along for the ride. As long as it is legal to do so, and adding color to things makes them sell better, people will continue to add the glitz.

>A leap year is a year that has an extra day. This extra day is added at the end of February: February 29th. It's added every four years because Earth does not actually take exactly 365 days to orbit the Sun, but closer to 365 1/4 days. If not for leap years, we'd gradually shift our calendar relative to Earth's orbit.

FYI: In the beginning, the leap day was actually added in between days in February and all patron saints coming after that leap day moved one day over.
Later, the leap day was indeed added at the end of February.

Download speed depends on a lot of factors, not just the speed of your connection. It also matters how quickly the server can send the file to you, and the speed of intervening links in its path to you.

Think about it like a big road network. Your computer is like a warehouse with a big loading dock and several lane road coming to it. Even if you can accept and unload 10 trucks an hour, if the supplier can only send 5 trucks an hour that is how much you will get. Different suppliers can send different numbers of trucks but it would max out at however many your road and docks can handle. It might also be the case that road work between you and one of the suppliers slows traffic so only 3 trucks an hour get through, so neither you or the supplier is the real limiting factor.
