I worked for this chiropractic office as a massage therapist while taking my pre med/art studies.  I developed a series of streching exercises and illustrated them.  I gave my work for free to the office and the office charged only a nominal fee to cover printing, so that anyone could afford them.  The more I've given whole heartedly, I've found, the more I've received - just talking from my experience.  I loved helping to heal and give comfort to the people who came to our office.
