I’m a doctor and I play one on the Internet. Not an MD mind you, but a PhD. I have a dual concentration Metallurgy and Biomedical Engineering. I bring this up not for braggadocio but for credentials. So when I touch on matters of biomechanics, anatomy, and physiology, I am speaking with some level of authority.
In one of Miguel’s previous posts he quoted from some CSGV blowhard (emphasis mine):
“They are so terrified of having a simple physical confrontation (i.e., shoving match, fistfight)–and so bitter about what it might do to their pride and reputation if they come out on the losing side of the equation–that they would rather shoot and kill another human being than stand up and face that situation (which frequently is of their own making).”
I’ll admit it, I am terrified of getting into a fistfight. I’m not gonna take it outside. I’m not gonna settle it like a man. I will do everything I can to avoid a fight, and if that means I have to shoot you, guess what, I’m gonna shoot you (which believe me, I’d much rather not).
Here is why, in three words, I do not want to get into a fistfight: Traumatic Brain Injury. The human brain is made up of relatively inelastic tissue, neurons and capillaries. The brain sits in a sack of fluid called the dura matter. This is inside the skull. When you take a punch to the head, your head goes from still to moving very quickly. This linear and rotational acceleration causes the brain to smash around inside of your skull like dice in a shaker.
Every time your brain hits skull, it stretches. When your brain stretches it tears, neurons rip away from each other and capillarities rupture. Your brain starts to bleed. Blood collects in the spongy tissue of the brain compressing it. The brain starts to swell, squeezing it inside of the skull. This compression and the torn blood vessels causes a loss of blood flow to regions of the brain. Without blood, there is no oxygen, without oxygen, parts of the brain shut down. Long enough without oxygen, the brain dies. When the brain dies, so do you.
A solid punch can cause your brain to smack around inside your skull with the force of a high speed car accident. And no, it doesn’t take a professional boxer to kill with with a punch.
I like my brain. I spend long enough in school stuffing it full of facts. I’m not going to let somebody try an kill it to prove my manliness. Assuming that I survive, of course, it would me nice to still be able to come away remembering how to do math, or even my kid’s name.
