Although it seems as though your question is sarcastic, I'll give you a real answer anyway.
I've been slowly becoming more observant in Judaism over the past couple of years, and I've come to understand that one my roles as father and husband will be to be the "Rabbi of the house"; the person who knows Torah, who can answer questions, and who can pass his knowledge down to his children. Many observant Jews are born into such a family, and have gone to religious schools where they are taught Torah ethics and law. This prepares them to be a better father, husband, and person later in life. Because I did not grow up in such a family, I have a lot of catching up to do.
I planned to go to Israel to study Judaism in the summer before dental school. I knew that a few months would not be sufficient time, but it was all I could afford to do. In January, however, I met a person who graciously offered me a full scholarship (flight, room/board, tuition) to study in Israel for over a year (15 months starting in June). It was an opportunity I could not ignore, especially since after dental school I will probably have hundreds of thousands of dollars of unsubsidized debt, which means I would have to immediately start working to pay it off. I wouldn't have the time or money to do this until way into the future, which would be too late because the point is to be prepared for marriage and raising children (which I hope to do during or soon after dental school).
So, because I had already applied and gotten into schools when I was offered this scholarship, and because I'm a borderline applicant with a 3.3/3.18 GPA and 19/18 DAT, I felt like it would be better to try to defer than to try to reapply.
