Blood

Blood is one of the many fluids you (sometimes) shouldn't bleed out. It is a red, vital bodily fluid, accounting for 7-8% of one's total body weight. It primarily circulates nutrients, respiratory gases, immune system components, body heat, and hormones while removing waste.
Jews often drink the blood of goyim and their children to sacrifice them to Moloch;[meds...] animal blood is not kosher though.
You have a special series of canals in your body known as the bloodstream, which is the path blood circulates in. If you don't have blood circulation to an affected part of the body then that part of the body fucking dies.
Blood, when it starts to rot or become low on oxygen, becomes brown like poop, although it is bright red when directly leaving the heart.
It is also the name of a gemmy 1997 FPS game where you shoot up zombies and demons or something.
Similarly to raw milk and raw meat, the government fearmongers consuming blood because they want you to be weak, docile, and easily controlled, but in reality it is one of the most nutrient-dense foods you can consume. It is full of life force (literally).
