This book changed my perspective on basically everything having to due with light. Information is presented well and extremely easy to understand, and he uses a lot of examples from patients and other stories. He really emphasizes the need for doctors to be empathetic and truly connecting with their patients, rather than the cold and de-personalized doctor-patient relationship rampant today. There is so much valuable information about the human body and how intrinsically linked our body is to the sun that it's improbable you'll walk away without something to consider. I hardly knew anything about the subject until I read this book, and it's inspired me to apply many useful tips and lessons learned from others. Light and how it's received is so important to the quality of life, and plays a part in almost all types of ailments, yet I knew very little about any of it! So needless to say, I'm grateful to Jacob Liberman, from the bottom of my heart. Thank you for writing this book. I hope you read it too.
