I like this visual that all sickness is essentially molecules misbehaving.
In fact, I heard something similar to this in regard to cancer once.
Essentially: Cancer is an immune disease.
Or said different, where cancer is found, the immune system is not working as it should.
In the end, we can’t get out of that talk of death though, can we? Not eventually.
And as I sat there, I realized that the questions intersecting life, death, and meaning, questions that all people face at some point, usually arise in a medical context. In the actual situations where one encounters these questions, it becomes a necessarily philosophical and biological exercise. Humans are organisms, subject to physical laws, including, alas, the one that says entropy always increases. Diseases are molecules misbehaving; the basic requirement of life is metabolism, and death its cessation.
