     How TO AVOID DISEASE, HOW TO BREED SUCCESSFULLY and how to live to a reasonable age are plexed mankind throughout history. This book explores our progress in understanding these challenges and the risks and rewards of our attempts to find solutions. Nutritional experiences and exposure to microbes and alien chemicals have consequences that are etched into our cells and genomes. Such events have a crucial impact on development in utero and in childhood and later affect the way we age, how we respond to infection, and the likelihood of our developing chronic diseases, including cancer. The issues covered include the powerful influence of infectious disease on human society, the burden of our genetic legacy, and the lottery of procreation. The author discusses how prospects for human life might continually improve as biomedicine addresses these problems and also examines the ethical checkpoints encountered.
     Michael G. Sargent is a research scientist in developmental biology at the National Institute for Medical Research at Mill Hill, London.
