Jeanne Calment, a person with a life span of 122 years, was born in 1875 and died in 1997, was the longest living person on record. This wonderful French woman took up fencing at the age of 85, and was still able to ride a bike when she reached 100 years old. She walked around her hometown, Arles, in the south of France, to thank the people who had sent her birthday wishes on her 100th birthday.

On the other hand, in contrast to Calment, there are people in their middle age who suffer from chronic diseases, have weak immune systems, low energy levels, looking weary and 10 years older than their peers. Why do people age at different rates? Why do some people stay energetic into old age, while others who are much younger, are sick, have foggy brain, and suffer from ongoing fatigue and tiredness? What is the secret behind aging? The Telomere Effect explores aging down to the cellular level, and reveals the secret of how the environment and mental status affects the speed of aging in humans. The book then provides suggestions on diet, sleep, sports, followed with tips on how to change our way of thinking to help us slow down aging and be more energetic.
