Posture:
When sitting at a computer or in the car a person's eyes should have a central view when the head is in the correct position. If this is not the case, the height of the chair should be altered accordingly.
As a person becomes more stressed and tense the shoulders automatically tighten and rise
Heavy begs and children carried on one side of the body alters alignment, causing excess stress in corresponding muscles.
High heeled shoes will cause the knees to lock in an attempt to mantain balance, putting excessive strain on the knee and ankle joints.
