Dream big. Set ambitious goals. Attain unusual achievements.At the age of 68, while still recovering from his second knee injury, Dr. Zeev Gilkis decided to give himself an unusual present for his 70th birthday. He dreamed of running a full Marathon, and completing the seventh decade of his life seemed to him the ideal timing to do so. Perhaps this ambitious goal wouldn't have been so unusual, had he been a very physically active person in his younger years. But Zeev is a cancer survivor who began his 'career' in sports relatively late, in his mid-sixties. As two years is a long time, he set a milestone for his 69th birthday: to go mid-way - running a half marathon. Along with his plans and dreams he kept a diary where he recorded the ups and downs, practical tips and original thoughts that crossed his mind in this long, challenging journey. Join Zeev in this adventure and discover that age doesn't matter. You too can achieve anything you truly dream of. In his first two books: Unlock Bliss, A Memoir of Getting Happier and The Secret of Life, A Memoir of Getting Younger, Dr. Zeev Gilkis shares with readers the story of his struggle with cancer, some important and original thoughts and insights into life and happiness, such as that "Age doesn't matter!" among many others. In a very simple writing style, he describes some of the key processes in the brain, the role of the immune system and how to care for it, the story of how he got into sports in his sixties, and much more good stuff.
