So you want it all. I believe strongly in the mind/body experience, and as a healthcare provider I can tell you stress is a killer in many way, anxiety , etc ,but medical attention is needed. While the mind body can deter illnesses, sooner or later a body breaks down or one is born with bad genes. It will only get worst, if they kill the EPA, and the food we eat is full of chemicals to begin with . A relaxed unstressed mind can create a environment more conducive to health and healing. For some that might be in the form of prayer and meditation, or exercise, but there is a need for medical intervention sooner or later, and if your lucky enough to never have an accident or illness and just keel over and die when 85, good for you, but that is not the norm.
