You can get a brain aneurysm at any time. Some factors exacerbate them, sure, but sometimes it’s genetic.

Mammary glands are modified sweat glands. Milk is just essentially chunky sweat.

We have about 100,000 different types of proteins in our body, but only about 22,000 different genes. Some mechanism we don't understand yet "spells" the amino acid sequences for our proteins by combining the RNA transcribed off of various different genes in highly sophisticated ways such that the majority of our proteins are not directly encoded in their entirety in a gene of their own.

This encoding system has all the features of digital information management: it has compression, error correction, polymorphism, inheritance (in the sense of object oriented programming), and others that we don't have corresponding technologies for. It is incredible how sophisticated our hereditary system is.

Your eyes are not part of your immune system, and if your immune system ever discovered them, it would attack them.

That's why if someone is injured in one eye, they could potentially go fully blind due to the immune system "finding" both eyes due to the injury.

The human body is constantly eating itself, a process called "autophagy".

Mitochondria is not a natural part of your body. it's more like a living bacteria that live inside your cells for mutual benefits.

Your immune system does not actually know your eyes exist and if it ever finds out, it will mistake them for foreign parasites and permanently blind you.

You can’t move your upper jaw, it’s fixed into your skull. All that movement in your mouth is produced by your lower jaw and tongue. This realization gave me a claustrophobic feeling.

Your brain can chew itself to pieces under stress.

Farts can be deadly on the operating table, due to bacteria spreading.
