Tires â Retreading is less expensive than new tires and is a large portion of this cost. Although mere pennies per mile, an average tire can cost over $250 and annual tire expenses can exceed $4,000 ($0.03 per mile), enough to purchase 16 new tires annually, but still not enough to replace every tire of an 18-wheeler.
To Correct Forward Head Posture, the muscles which need to be stretched comprise of: 1  Upper cervical (capital) extensors: Semispinalis capitis, splenius capitis, longissimus capitis and suboccipital muscles. 2  Lower cervical flexors. Sternocleidomastoid muscle, medial and anterior scalene muscles.
Transversospinalis: The Deep Muscles of the Spine. There are three layers of muscle on the back of the body that are associated with the spine and stretch from the pelvis to the head. These deep muscles of the spine are largely responsible for maintaining posture and moving the spine. From my humble perspective few of these muscles are being accessed successfully. If you are familiar with what I am on about, my take is that everyone habitually leans backwards through life.
