In Mexico the government has their own health care system, if you are a Mexican citizen you have access to it for free (if you are a student or you work legally), it’s sustained by taxes that employers pay to the government, there are two health care systems IMSS and ISSSTE, depending on if you work for the government you get one or another.
These institutions will give you the treatment that you need and surgerys as well, except cosmetic stuff. Since these institutions aren’t optimal (usually takes a long time to get attention) you might prefer to use a private health care, and you just pay a private company for what you need or pay monthly for an insurance plan, which will cover certain hospitals and specific diseases
I’m not an erudite so feel free to correct me c:
Wayland is a new implementation on how your system draws windows and components in your computer (I’m not sure if it’s responsible for the content) and it tries a different way to do it compared with xorg.
Xorg is the old implementation, and it has been patched to support most of the new features, and Wayland is trying to get the same features xorg has and some extras.
As a Linux user I have noted that sharing screen is more private in Wayland, also I think multi monitor refresh rate was a problem in xorg. One common issue with Wayland is the GPU compatibility, as far as I know Wayland runs better in AMD GPU I think is because of Mesa integration.
