As an athletic trainer, I describe it like so:

Think of your muscles as a rubber band. If its cold, then its more at risk of snapping under load. To warm it up, you stretch it gently repeatedly. (Dynamic stretches) You don’t stretch it to its max and hold it there. (Static stretching) You’re just exhausting the elasticity. Saving static stretches for after activity keeps the rubber band from bunching up and sticking together as it cools down again.

An injured muscle could be described as being “colder” or like rubber bands stick together sometimes. And the best way to fix them is to work them back to normal in a controlled manor.

That butt looks like every overweight person’s butt ive ever seen lol

Because sometimes its better to not ask if you can or should and instead try. It was obviously popular enough that it still has a soft spot in many tech enthusiasts’ minds. And arguably its the element of any OS that you encounter the most. Going from your home computer to even just a computer at the public library, one thing was almost guaranteed to be the same and that’s the desktop background.So why not make it really high quality? They had no idea how far resolution would come and what would end up being sufficient, but because of their decision, even now people seek out that image for their desktops.
