The book Keep Sharp: Build a Better Brain at Any Age is a testament to Sanjay Gupta’s passion for neuroscience and his genuine love for people. The book has three parts. In Part 1, Sanjay demystified the complex subject: the human brain, allowing us a peek into what he sees as a neurosurgeon. Part 2 is about the lifestyle that nourishes a healthy brain. It does not merely tell the reader what to do; it explains why that kind of lifestyle is necessary. The proposed program is not forced on the reader; instead, it encourages the reader to know what will work best. In Part 3, we vicariously experience the pains of the diagnosed person and the caregiver. Throughout the book, the reader will feel Sanjay’s pride and hope towards past and ongoing neuroscience research.
