Long, black, outweigh, chase me off.

When you strangle someone, you not only cut off their airways.

You violate every cell in their body.

Not in some fancy, poetic sense, but as a biological fact.

Every cell in the human body needs oxygen to survive.

And when you take it away, you spread death throughout every part of them in which oxygen used to flow.

The science of all of this is pretty straightforward, the corroded arteries that carry blood into their head continue to operate.

The jugular veins that carry blood out of their head shuts down.

Blood keeps pumping in, but it can't get out.

The jugular's leaving the head, therefore of them, are smaller in thinner and far easier to clamp down.

They're most prominent below the neck, and you can see them in the mirror above your clavicle heading down to the heart.

Your carotides that enter your head from your heart are deep in your neck behind your windpipe.

If you take your pointer finger and your thumb and place them on opposite sides of the top of your windpipe,

you can fill your carotids thumping on your fingers with a pulse of your heart.

These arteries are thick and muscular, and their depth makes them very difficult to stop.

So when you're strangling someone, the carotides keep pumping blood up through their neck to their brain that desperately needs it, which is great.

But this blood has nowhere to go.

The exits are blocked, the jugulars, monvomrable to the pressure of external clamping are more or less kinked like four little backyard hoses.

The blood vessels in your victim's head now overloaded, begin to swell under the pressure of all this extra blood.
