Dr. Lewis is board certified in Public Health and Preventive Medicine and has practiced medicine for over 25 years. He is a medical researcher, and the author of several books. He has worked with cancer cells, seeking anti-cancer agents with lower toxicity and in trying to better understand mechanisms of action at the College of Pharmacy and Pharmaceutical Sciences Institute of Public Health, at Florida A&M University. His goal in writing is to make complex topics accessible, and to promote use the understanding of science as a path to making people’s lives more joyful and fulfilling. He believes that a child’s work is to play and have fun, and that this should not change as we become adults. He aspires to being honest, thoughtful, and kind, although sometimes falls short of his expectations with the latter two. He notes that most of us find that life is difficult, but then we stupidly make it harder for ourselves and others. A goal in writing this book was to explore how we might learn to live kinder, more pleasant and fulfilling lives.
