Well said. I said the immune system should be to blame in the previous thread and was downvoted to hell. But it’s true. What’s more, it’s highly under appreciated that the immune system is extremely ancient and it does a lot more than the typical things associated with it like destroying tissue. It pulls deep metabolic levers that can make critical cells, including brain cells, latent. It can do many amazing things. In the future, the immune system won’t be known for immunity — it will be known as something like the second nervous system and will be associated with the nth great wave of medical progress when we finally conquer it and all the hundreds of diseases it causes. Diseases we don’t even have a name for now, I know for a fact.
