I had a conversation today that involved and led to some pretty interesting things, the first of which was a question. If you read this blog often enough, you know that I’ve written a few posts lately pondering the reason for human existence and such. The question was this – am I ok with the fact that I may never have an answer to that question? That I may have to take a stand and come to my conclusion with insufficient or incomplete information? The answer to that, in short, is a resounding no. Actually, “Hell no” is probably more appropriate. I am not ok with having a question that I will or may never have an answer to. I never have been. I think that’s the drive behind these posts. I’m searching for the answer, and talking myself through the logic and the available data. It’s what I do.
I should also add that I need to have answers that I can understand. Not necessarily agree with, but understand the reasoning or logic behind. That’s part of the reason I lost faith in God. I had a question when I was younger, and the only answer I could get was, “It is God’s will.” or, “God works in mysterious ways.” These answers, to me, were bullshit. Flat out. Because I needed to know why, and the only answer I could get is because some dude I never met who has more control over my life than I do wanted it that way, or because said dude was doing some straight up sneaky shit and fucking with my life in the process. Even before that, I always had to understand the answer. It has to make sense to me. I’ve driven some people in my life crazy with that.
Anyway, back to the question from today. No, I’m not ok with that, but on a side note, who says I have to come to a conclusion with incomplete data? I don’t have to do that. I have signed no contract, there’s no gun to my head. I can search for and think about this question until the end of my days and if there is no point at which I can comfortably come to a conclusion, so what? What happens? I die with a question on my mind. Big fucking deal. I can tell you this though, if that ends up being the case, I will not die with the regret of never searching for the answer.
Another interesting thing that came up today was a theory. This is a theory that is intertwined between neurology and psychology mainly, but takes tangents into cardiology, gastroenterology, and evolution. I’m talking about something called polyvagal theory, or PVT. I’ve done limited reading on this, but after today’s conversation, will be doing more. The human body has, according to accepted science up to this point, two main components of the nervous system. There’s the sympathetic nervous system, responsible for the “fight or flight response” that we’ve all heard so much about. Then there’s the parasympathetic nervous system, which is responsible for the opposite set of functions, also known as “rest and digest”. These two systems work to keep your body in balance. Being chased by a lion? Ok. Sympathetic nervous system kicks in, pumps out adrenaline and cortisol, increases heart rate and helps you run for your life. Made it to a tree or cave or the lion gets fed up and stops chasing you? Awesome. Parasympathetic nervous system takes over, calms you down and lets you rest for tomorrow’s adventure.
Polyvagal theory, at least from what I’ve read so far, further divides the parasympathetic nervous system into two branches. The dorsal vagal system and the ventral vagal system, dorsal related to the back and ventral related to the front, belly or underside. The dorsal vagal system is related to not only the “rest and digest” function, but also the “freeze” response – the deer in headlights. The ventral vagal system is responsible for components of social interactions, and actually has a hand in regulating the “fight or flight response” of the sympathetic nervous system via these social responses. Now, there is much much more to this than what I’ve said. Again, limited reading so far. But, fascinating, nonetheless. (Side note. Apparently, there is information in the literature that says that the dorsal vagal system is the most primitive, which actually makes sense from an evolutionary standpoint, because the first component of the complex nervous system to evolve was the chordata, which evolved to and is known in human and mammalian anatomy as the spinal cord, where all of our reflexes and other involuntary responses come from.)
Finally, part of this conversation about the parasympathetic nervous system led to a discussion of the fact that I rarely take enough time to rest, and almost never take a vacation. True statements, though I’m actively working on rectifying the first part, at least. I went through some stuff a couple of months ago that has prompted a great deal of my current thought process, and to be honest, I’m grateful for what happened and the changes it’s bringing about.
I think that’s enough rambling for now, I need sleep and have to work in the morning, like so many other people.
Have a great night!
