I've been wondering the same thing, and would also like some opinions.
Also, for the ".unique experiences or obstacles that you have overcome " question,. do you folks think it would be appropriate to discuss the undiagnosed/untreated Celiac disease I had growing up? It was misdiagnosed at least a dozen times (usually as a psychiatric problem, such as "attention seeking" or as anorexia.....in a 6-yr-old!) before being properly diagnosed in my 20's, and it caused me (and my family) a lot of pain and emotional suffering (at certain points in my life I was literally starving, and I looked like it). I just don't know if if would be construed as too dramatic or personal. My diagnosis was a big "why medicine?" inspiration.
