An old slogan FedEx used to use was "When it absolutely, positively has to get there overnight."

Mental Impulses are the life messages/information the brain sends to all the cells, tissues, and organs of the body via the spinal cord and nerves.

Those messages absolutely, positively MUST go from the brain to the parts of the body and back again, not just over night, but every moment of your life for your body to function properly.

A subluxation is like a roadblock that prevents the messages from getting through properly.

An adjustment is the way that chiropractors remove that road block, restore proper traffic, and allow those messages to get through so you have the potential to function as close to normal as possible.
