I belong to family Of Doctors. I spent my +2 prep for entrance exams with the hope that I would get through in a govt medical college.I spent the next 4.5 years of MBBS studying. MBBS is a course which cannot be described in such a short space but suffice to say that it is based on "Survival of the fittest". Daily Lectures,Attending Seminars, Practical Classes,field surveys & lots more..
Internship was filled with 24 hour hectic duties. Though Night Duties Were Full Of FUN. It might sound odd to some non medico as to how someone can be awake for such long hours.
On a bright side you have experiences which u can only have in this field. The joy of delivering a baby, the thrill of doing a surgery, the fact that you are doing something which would in all probability change the outcome of your patients whole life.
As a whole, its a tough field with long work hours, huge responsibilities and an experience which will set you apart from others.
