This is just my opinion, but the feeling that I get from medical schools is that reapplying is almost a right of passage. It is just another way to test how you handle failure. Some people will decide they can't get in and give up, others look at their weakness in their application, improve it, and come back stronger.
In the rejection letters I got from several MD schools last year they told me to call the office of admissions and find out what my weak spots were, then to reapply.
