Introduction

Abstract

I guess everyone has a cousin Ernest. He is the fellow of whom your mother asks…“Why can’t you be more like your cousin Ernest?” Cousin Ernest went to the high school for genius children and got all A’s, even in French. As the years went by, I lost contact with Cousin Ernest. Then last year, at a family gathering, I met him again. Sure enough, he had gone to Harvard and become a doctor, a radiologist.
