"Also, your spine might be a little malformed... in which case there is nothing that you can do..."
Sorry Shamou,
Chiropracter or not, this statement is nonsense. Most spinal issues are really postural issues therefore issues of the myofascial structure. Much can be done to relive lordosis, herniated discs, scoliosis, kyphosis, spondylitis. More often than not these problems are a result of a lack of full range movement. Posture can certainly be affected by exercise, I'm proof of it.
