The good news is that postural changes can be corrected. The bad news is that postural changes are ignored and can be prevented.
Why is posture so important anyway?
The spine is designed to house and protect the spinal cord. Nerve bundles run from the spine to all the organs and tissues of the body. The spine is kinda like the fuse box of a house. When the occupant of the house turns on the microwave the power connections run from the microwave to the fuse box coordinating the power.
What happens if a fuse is blown?
Easy, you will not be able to microwave your leftovers from last night.
The same goes for bad posture. When our spine is not functioning correctly the other systems of the body are affected too. These affects are called symptoms.
