Thirty-two-year-old John Wood is a surgeon at a famous Boston hospital. "During the first two year of high school, I found biology very difficult. My report cards always said things like 'must try harder' or 'John ought to choose non-sciences. ' This was a disater for someone who had always dreamed of becoming a doctor. I was so discouraged that I dropped out of high school at 16 and stared wotking at a local supermarket.
