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.
Okay true, but you also need deep sleep a lot otherwise you dont regenerate. Also the body is fully K.O. which may make more sense
I get very little deep sleep. Is that part of why my injuries take so long to heal and feel like shit all the time
