For me it is the fact that our blood contains iron. I earlier used to believe the word stood for some ‘organic element’ since I couldn’t accept we had metal flowing through our supposed carbon-based bodies, till I realized that is where the taste and smell of blood comes from.
I suppose it is for the best, but nonetheless I find it uncomfortable how our bodies have the ability to manipulate our brains’ memories and our consciousness residing in the same place cannot do anything about it
Oh, it’s worse than that, the consciousness is in on it.
These chemicals are our memories. They aren’t manipulating it. It’s just how it works.
On another note: the body produces opioids when you’re in great pain
