The greatest miracle on Earth is the human body. It is stronger and wiser than you may realize, and improving its ability to self heal is within your control.

The complex structure and design of our nervous systems is so that all parts of our bodies can communicate with each other by receiving and sending information through electrical or chemical means. For the most part, the central nervous system which is comprised of the brain and the spinal cord that runs the length of the spine, receives and sends information to organs, muscles, etc via the peripheral nervous system, which is made up of the autonomic and somatic nervous systems.
Being "well" involves addressing functional, biomechanical and behavioural factors to limit the recurrence of injury.
