Our bodies are carefully designed combinations of different tissues, organs and substances. The muscles, ligaments, bones, skin, blood, etc., which make up the various parts of our body have similar types of cells and appear very uniform. In fact, any cells that are not uniform are usually considered unhealthy. On a larger scale, everything is different. We have ears, eyes, hands, feet, etc.
Nothing is the same.
Even our hands are not the same, they are opposite so that they can complement each other. We appear to be a conglomerate that just happens to be functional. This same analogy works effectively for the chiropractic profession. On the outside, we seem to be a loosely knit group with extreme differences. We don't share the same philosophy, techniques, or rationale.
