Doctors are much more important than Teachers because;
1) Their role is to save peoples lives
2) Threat People for their diseases
3) Give advice to patients
Teachers are person who give the instruction, they don't carry out the task, just like how the software tells the computer what to do and the computer performs the task it the same thing in this case, the teachers give the instruction and the doctors perform the task.
OK take this example AIDS, teachers teaches about it, yes! they do but who is the one trying to find the cure for it, its that student and the student is the doctor. How can it be logical for a teachers trying to find out the cure for a disease, yes its important to know about the disease but it is even more important to try to find a vaccine to cure a prevent it and that the role of a doctor.
A disease is an abnormal condition of an organism that impairs bodily functions. In human beings,"disease" is often used more broadly to refer to any condition that causes extreme pain, dysfunction, distress, social problems, and/or death to the person afflicted, or similar problems for those in contact with the person.
Oh forgetting something teachers would not have experience with some type of sickness or diseases because they aren't the one experimenting on it and interacting with them daily. What Doctors do are far more important than what teachers do.
* Doctors save life
* Teachers teaches.
I did mention that doctors give advice, because the doctors has so much experience on that particular job, he can inform a teacher what to do and what not to do when she is pregnant or he has Cancer.
