This book is excellent, pushes the mind to think about life and evaluate your own life. This book reviews different people and their reactions to time, mirroring ourselves and our actions. Not in complicated text, even Einstein's brilliance failed him in his work on the theory of relativity, but even then there is enough work to influence those who analize his work. Very influencial, a book that makes you put it down and analize that last chapter before going on, because there is so much to realize that it must be taken in. Are we any of these people, do we live in any of these lives? A magnificent book that everyone should read...
