Why We Age explains the biology of aging in an all inclusive way for the first time. The author Dr Judy Ford has undertaken research in Cell Biology, Genetics and Public Health and is able to use her unusual experience to 'cross disciplines' and explain how all the pieces of the jigsaw fit together.

In the first part of the book she explains how chromosomes and cell division fit together with fat metabolism and cellular energy to cause age-related changes and what we can do to minimise the negative outcomes. In the second part of the book she looks at world data and how the facts add to our understanding.

This book can be enjoyed by all intelligent readers but those with a science or health related background will find it especially enlightening.
