The interests of young adults are more in tune with athletic performance than with preventing the diseases of aging. John J. Cannell, M.D., is reaching out to the young adult audience to help them be healthier for life, by teaching them how to become faster, quicker and stronger as athletes. However, we all can learn how to be healthier from his teachings. Dr. Cannell is a physician, scientist, researcher, teacher and perhaps most importantly, a health activist.
