On the Back of Unspoken Words, Whispered Silence

Why are you so silent? What's wrong?
Why won't you speak to me? What have I done?

When you stay this quiet, I get...
asphyxia.
Difficulties in respiration require oxygen cylinders.
The respiratory center stops.
Pain in the left fifth intercostal space.
Cardiac output decreases.
Venous return proportionally declines.
The heart refuses to pump anymore.
The hypothalamus won't get excited, or if it starts, it won't stop being inhibited!
The medullary center ceases.
Nervous control is lost.
The circulatory system stops circulation completely!
Coma,
convulsions,
and then
tends to death!
So, please...

Do you understand what's happening?
Sir, what I was saying is—will you open your mouth now? Or shall I dig through books for more words to frighten you a little more?
