I believe this is called an “impression”.

Yes, let’s make sure we’re on the same page. You’re talking about theory, I’m talking about practice - which, in theory, are the same. In practice, however…

They ended the ability of the Judiciary to check the Executive. That’s the very foundation of the government, set out in the Constitution: https://constitution.findlaw.com/article1/annotation01.html

So yeah, it’s the final nail in the coffin of the Constitution.

Adenosine is not a “waste product of neurons” in the sense it’s being painted. It’s a byproduct of energy production in all our cells, and what it does depends on the derivative - for example adenosine triphosphate (ATP) is used by the mitochondria in our cells for energy production! It then degrades into adenosine monophosphate (AMP) and from there into the CNS-depressing adenosine (or, it can be upregulated back “up the chain” by adding another phosphor to it).

As plain adenosine it can depress the central nervous system, resulting in feeling sleepy, slowing heart rate, etc, but adenosine levels are regulated closely by the body and the idea they can “build up until we die” due to lack of sleep is patently ridiculous. This article is a gross oversimplification that demonises a critical compound for no reason.

This article covers the detrimental results of adenosine overproduction in the body: https://pmc.ncbi.nlm.nih.gov/articles/PMC6398520/

While Wikipedia describes the compound more generally: https://en.wikipedia.org/wiki/Adenosine
