Yeast “lifestyle” is to eat sugars and pee out alcohol.
It is beneficial to yeast that alcohol is a poison to many other forms of life.
At around 16% alcohol dissolved in water, the mixture will kill even yeast.

Some forms of life (including Humans) have methods to use alcohol as a food using chemistry that is similar to how they use the “fruit sugar” fructose as food.
However, this chemistry first turns alcohol into the chemical acetaldehyde.
Acetaldehyde is an addictive drug to the human brain.
Once your brain gets addicted to Acetaldehyde it is very hard to stop drinking alcohol.

Drinking “Yeast Piss” can get your brain addicted.

Historically, Acetaldehyde addicts drop in number by about 10% every year.
Roughly 5% quit drinking.
Roughly 5% die

If you polled 1000 USA citizens at random,
less than 20% would give answers that show they know what is written in just a few sentences above.
