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.
 
The machine metaphor is very useful when we are considering aspects of human health and disease. For example, human machines need tuneups just as much and just as regularly as do mechanical machines.
Human machines that are "out of tune" break down. The nature of the breakdown may be minor or major, but it's never a good thing. Most of the time our health is transparent to us - we don't consciously experience our various body parts doing their job. Pain, however, is a notably conscious experience and one which is almost always unwelcome and unpleasant.

Regular chiropractic care is a convenient, efficient, and highly effective method of maintaining your personal human machine at peak levels of performance and structural integrity. Chiropractic care corrects the spinal misalignments that are common denominators in many, if not most, physical ailments and disorders. Chiropractic care directly addresses mechanical problems and helps ensure optimal functioning - optimal levels of health and well-being.

4 Reasons You Should Drink More Water!

You can go without food for days, weeks and even months, but going without water for just one day can negatively impact your health.

Many people don’t realize just how important water really is. The human body is made up of 2/3 (66%) water and when we lose just a little bit of water through sweat and elimination, and we do not replenish lost liquid, we’ll begin to notice the effects to our health right away.
 
Health Effects of Going without Water

Water is the most valuable life support product for our health, right up there with oxygen. Water and oxygen are the only two things in life that without for just a short period of time we would die.  Studies have been done that show if a 175 pound man were to lose just 2.5% of water in his body (2 quarts) he will lose 25% of his body’s effectiveness towards survival.
When a person begins to dehydrate more things happen in the body than just being thirsty. The more liquid in the body that is lost, the thicker the blood becomes and the harder the heart muscle must work to pump the blood through the circulatory system.  When a person loses their abilities to reason and think straight because of dehydration it means they will die very soon, unless they drink water to rehydrate. Depending on the circumstances, mainly environment, a person can die within 24 to 28 hours after having no water if they are laboring in the hot dry sun with no water. If a person is sedentary indoors and the elements, such as wind, sun, and heat is not present they may live up to 3 days, tops. So water is VERY important for survival, but water is also very important to your overall health.
Most people think they drink enough liquids throughout the day to keep them hydrated. But if you counted all the beverages besides water that people drink you would see that they are actually dehydrating themselves. Most liquids such as coffee, tea, soda, alcohol, Gatorade, and sugary fruit drinks do not hydrate the body like pure water can. Some people are walking around actually dehydrated and they don’t know it because they don’t feel thirsty. Let’s take a look at 4 of the main reasons you should make sure you’re getting enough water.

1. Fatigue and Tiredness
The first sign of dehydration is the feeling of being tired; some people experience a headache and feel like taking a nap. When the body begins to dehydrate it means the tissues and cells are not getting enough water to make a person feel like doing anything; enzymatic activity slows down and without water the enzymes are unable to produce energy either. In fact a dehydrated person may have no enthusiasm or joy for life.   The good news is once the individual starts to drink some water their energy reserves speed back up and sometimes the headache completely goes away.

2. Constipation and Digestive Problems
If a person is not drinking enough water they do not have enough liquid to help with the elimination process and without eliminating the foods we digest we gain weight, gain toxins, and feel awful.  Being constipated is the beginning to many health problems from allergies to toxic overload syndrome to digestive disorders, such as irritable bowel syndrome, gas bloating, stomach pain, nausea and loss of appetite in chronic cases.

3. Stomach Ulcers
To protect the stomach from its acidic digestive fluids that is made during the digestion of food, the stomach is coated with a lining of mucous, which are 98% water and 2% sodium bicarbonate.  Sodium bicarbonate helps in the digestive process by neutralizing the acids. When a person is dehydrated the stomach does not have enough liquid available to make the mucous, thus a poor mucous lining protecting a person from the acidic fluids the digestive process makes. This is why some people are more acidic rather than alkaline, and have digestive problems such as acid stomach and heartburn, which eventually without the alkalinity results in an ulcer of the stomach lining.
4. Weight Gain
Many times when we are thirsty we eat food rather than drink water. This can cause unnecessary weight gain, especially for a sedentary person. When your body is dehydrated, just a little bit, sometimes it won’t tell you with a dry throat or mouth, but rather with a feeling of being hungry.  Here’s the thing, if you just ate a sufficient meal not too long ago how can you really need to eat again?
To know if you need water or food, next time you are hungry when you have already ate a meal, drink a couple glasses of pure water. If the hunger pangs subside you’ll know you just needed to feed the body some water. The body needs at least 2 to 3 liters of water a day, and drinking more than that will keep you from feeling hungry. Not only that, but it will also help you eliminate more toxins from your body. Eventually your body will stop telling you it’s hungry because you are maintaining hydration throughout the day.
When you drink enough water throughout the day you are feeding the tissues and cells in your body and that gets the enzymatic system moving, which actually releases fat toxins out of the body! Now isn’t that good news? Rehydrating the body through pure water gets your metabolism running in full balance rather than being slow and sluggish, which is a cause of weight gain.
Do you want to add some vitamins and zest to your water? Then squeeze two or three lemons or limes into each liter of water and drink this nourishing water throughout the day. The great news about this is you probably won’t catch a cold anytime soon! Drink water for your health!

Drink Pure Water
Some water sources are not clean even though many people drink from them. Well water can be full of toxic inorganic minerals that could be making you sick. Bottled water isn’t necessarily any better, you still need to know where it came from and what is in it. Minerals on rocks build up into a sludgy scum and then you drink it. Tap water in some cities is also very mineral laden and too much minerals will cause arterial problems. Water should be as pure as possible, without minerals and bad bacteria.

Inorganic Minerals that could be lurking in your Water

Aluminum Arsenic Asbestos
Barium Cadmium Chromium
Copper Fluoride Lead
Mercury Nitrate Nitrite
Selenium Silver    

Minerals and vitamins should come from the purest source, which are organic foods that derive from plants or animals. If you think you might be drinking water that is dirty with inorganic minerals you can have it tested. The safest and easiest thing to do to ensure clean water is to buy a good water filter or softener to put on your faucet that filters out mineral toxins from your water.
