This reminds me of my debate club during my high school days. Well the topic under review is not something a a clean line can be perfectly drawn but I'll make just a statement in support of the medical doctor and that is, the very life you try to sustain existed because of help from the medical doctors. You'll never know how important the medical doctor is until a mother is in labor to deliver the almighty farmer. If our being in the first place was made possible with assistance of the doctor, permit me to say that both professions are symbiotically related and no clean line should be drawn between them. I rest my case
