"the world of medicine and biology" - Johns Hopkins Which major and why

Here is the first supplement question from JHU. Any suggestions are welcome, and thanks in advance!

Johns Hopkins offers 50 majors across the schools of Arts and Sciences and Engineering. On this application, we ask you to identify one or two that you might like to pursue here. Why did you choose the way you did? If you are undecided, why didn't you choose? (If any past courses or academic experience influenced your decision, you may include them in your essay.)

My first patient was a short nine year old female who persistently complained of having sharp ulcer-like pains around the stomach coupled with slight cranial pressure. After a quick examination and some deliberation I prescribed two scoops of chocolate chip iced-cream and in no time, her head and tummy ache vanished and she (my sister) was cured. Although this was almost a decade ago, my fascination with the human body has withstood the test of time and maintained its place in my life.

I remember on a few occasions I would go so far as to avoid going to the doctor in an attempt to figure out the problem at hand. I saw it as a challenge to use whatever knowledge I had along with the resources at hand (internet, medical books around the house) to formulate a hypothesis and thus a diagnosis of my own. Though my intense curiosity and desire to learn more caused me to make a less than ideal decision, it allowed caused my passion and love for biology to grow astronomically.

With the Johns Hopkins Biology Department hosting 27 research laboratories and the prestigious Hospital being in close proximity , I would have a bird eye's view into the world of medicine, a practical mastery to go with the theory knowledge obtained and essentially all the necessary resources available to ensure my being well equipped to take on any necessary task.

LOL i love this,it's funny how it turns out to be ur sister. Well, for the content, i think it's really intriguing. good luck
