Man and Machine

Is a computer like a human brain or is a human brain like a computer? When machines allow us to extend our abilities, are we enhancing our humanness or becoming more machine-like? What are the meaningful distinctions between humans and machines and how do these impact our daily pursuits of health, well-being, and happiness?

One primary practical distinction is that humans initiate spontaneous, unique, non-predetermined actions and machines do not. Advanced machines such as military early warning systems may initiate spontaneous activities, but all of these are predetermined and predefined to a greater or lesser degree. And for any machine responses that are not previously designated and programmed as routine, human interaction is required for initiation of the suggested action.

Generally, even the "smartest" machine only has access to a built-in suite of responses. Noted exceptions include computer programs based on simple rules which emulate living systems. The "cellular automata" generated by these programs demonstrate spontaneous emergent behaviors not predictable from the simple rules themselves. The "artificial life" thus observed is exceedingly complex and can even provide optimal solutions to deep scientific problems posed to the system by investigators.

Cellular automata are examples of complex systems, defined as systems which are critically sensitive to small changes in initial conditions. Complex systems achieved fame in Michael Crichton's novel (and the subsequent Stephen Spielberg film), "Jurassic Park". In the book, the paleobotanist Dr. Ian Malcolm uses the weather as an example of the nature of complex systems. In a scene which has achieved iconic status, Malcolm relates how a butterfly flapping its wings in the Amazon rain forest can cause a tornado in the American Midwest. Small changes in a complex system's initial state can lead to substantial unpredictable results in the system as a whole.

The human nervous system is such a complex, dynamic system.1,2,3 Small changes in the nervous system's initial state can result in dramatic outcomes. For example, a spinal misalignment (resulting from an innocuous low back muscle strain) can irritate a spinal nerve (a small change in initial conditions) which can lead to chronic indigestion, allergies, migraine headaches, or even high blood pressure down the road.

Most machines are not complex in this way, but they do require regular maintenance and care. As human beings, we are complex systems by our very nature and the importance of regular maintenance and care is that much greater. A healthy spine and optimally functioning nerve system go very far toward ensuring the health of our body-as-machine and our associated happiness and well-being.

  • ""I was very impressed with the chiropractic care I received . I had received chiropractic in the past for my neck pain, but not to this level of care. After only a few sessions, my symptoms began to disappear, especially my neck pain, and I know I would not have been able to perform to my everyday work functions without the treatment I received.""

  • ""As a court reporter, using my hands to type on a daily basis is a requirement. The work is speedy and can often last for hours at a time. Several months ago, every movement I made became excruciatingly painful. I started seeing Dr. Traficante and got started on a program that helped right away. The doctor stressed the importance of my posture and proper hand and arm placement.""

  • ""I have benefited tremendously from the chiropractic care I received from Traficante Family Chiropractic. Not only has the adjustments helped alleviate my stiffness and aches, but it has helped me have more energy and just feel more balanced over all. A few months ago, I was able to resume a favorite hobby of mine - golf. Due to my previous pain, I never thought that’d be possible.""
    John M.
  • ""Dr. Brandon has allowed me to be headache free for quite some time now. I used to have daily nagging headaches that often would turn into a migraine leaving me unable to function. For the longest time, I thought I could just keep taking medication to have the pain subside.""
    Christine F.
  • ""Dr. and staff are so nice and take time with each of us. I never feel like they are in a hurry. Always works with my schedule . I live in Buffalo Mills and travel clear to Altoona so you know he is good. Thanks for all you do for me and my family""
    Joy M.
  • ""Wonderful Drs. The staff always fits me in in short notice which is very helpful for my life. They are always patient with my children and I usually leave feeling much better!""
