Self-help ✦ Penny’s Take
Longevity Guidebook
Peter H. Diamandis · 2024
65/100
👎 Skip It
Peter Diamandis writes accessibly and covers genuine cutting-edge longevity science with energy and breadth — this is not a lazy wellness book. But the undisclosed conflicts of interest are a real problem: many recommendations align with companies he has invested in, the full protocol costs over $30,000 a year, and the optimistic framing outruns the scientific consensus in places. Worth browsing for the lifestyle fundamentals chapter, but read with a healthy skepticism about whose interests the biotech recommendations serve.
