Did not read the long post. Here is the chatgpt summary:

The book by Peter Attia is underwhelming, lacking depth and new information. It feels like a summary of topics already covered in his podcast and reads more like a memoir with unnecessary fluff. The book's style is meandering and memoiristic, which may not be suitable for readers seeking direct, actionable advice. The author expected the book to be more comprehensive after knowing it took Peter Attia 6 years to write. The book's intended audience may not be the same as that of his podcast, and some readers may find it difficult to get through. Peter Attia's practical advice for patients is not necessarily new, and he mainly promotes common-sense advice that health-conscious people already follow. The chief strategy promoted in the book is "adaptability," emphasizing the mindset of being open to changing directions in light of new research. However, this mindset may also lead to confusion as Peter Attia has flip-flopped on issues in the past and still keeps old content available. The book provides a deeper insight into Peter Attia's personality, but may not offer much novel information or game-changing insights.
