I think it's best to get the reader's attention by starting at a compelling point of your life. The "I was born...." is really boring.
I have had to read a lot of autobiographical essays of people who applied for internships and scholarships, and the essays that stand out begin with flair by NOT saying anything like "Let me introduce myself," or "My name is" or "I was born...."
Northstarmom, definitely has a point. Something to consider would also be choosing to begin your autobiography at the point where YOU felt YOUR life began. Basically, rather than entertain the presumption that life begins at conception or when you are delivered, why not discuss your life from when it began-in your mind.
