I was very pleased to be asked to contribute some illustrations to 'The Longevity Book' by Cameron Diaz, which has recently come out. The book is a follow up to 'The Body book' and is a personal, practical guide that examines the art and science of growing older. My illustrations are similar to those found in a biology text book but perhaps a little softer in style. Top to bottom are senescent cells, cell diagram, neurons and X and Y chromosomes. The book is published by Harper Collins.
