Aristotle was the first biologist in the scientific sense.  That is he is the first biologist in the scientific sense for whom we have a record.  Therefore it is possible there were prior biologists in the scientific sense.  He was the first to complete a record of specific observations concerning living matter’s structure and behavior.  He was the first to compile this record within a system and apply theory to this record.

Chiropractic is a system of therapy manipulating the spine.  The spine houses a critical portion of the nervous system.  It is the Interstate Highway carrying neural traffic efficiently back and forth.  The chiropractor makes sure the bridges stay put, the potholes repaired, working with the cause of your health problem instead of its outward effects, removing the subluxation in your spine and allowing the innate healing power of your body to cure naturally, regaining the normal healthy condition nature intended you to have.

Biology is the science of living matter in all its forms.  Biology is the science of living matter in all its phenomena.  Biology is the phenomena of an organism.  Biology is the phenomena of a group of organisms.  Biologists are scientists.  Chiropractors are civil engineers.   They ensure your bridges stay put and potholes repaired, working with the cause of your health problem instead of its outward effects, allowing the innate healing power of your body to cure naturally, regaining the normal healthy condition nature intended you to have.
