We are indebted to our medical editors for their constructive criticism, efficiency and advice. Sheila Adam would also like to thank her husband, David Fathers, and children, Florence and Alex. Sue Osborne would like to thank her partner Mervyn and children, Ellie and Joshua. Without our family’s patience, encouragement, and enthusiasm this book would not have been possible.
