Compilation Of Errors Undermined The Book

- That pattern argues against simple claims that 'shorter sleep shortens lifespan' causally.

- Walker cites daylight saving time as a global sleep experiment causing heart‑attack spikes, but data sources are small and inconsistent.
- The strongest explanations for crash spikes are darkness and timing, not simple sleep loss.
