Host Dave Asprey breaks down why sleep deprivation is just another form of brain energy stress, how creatine's phosphate-buffering mechanism stabilizes ATP in the prefrontal cortex under pressure, and why this changes how he thinks about red-eye flights and all-nighters. Vegetarians and women showed the largest effects ... your baseline diet sets your ceiling.  Sources:  https://pubmed.ncbi.nlm.nih.gov/42075005/   https://www.nutraingredients.com/Article/2026/04/21/single-dose-creatine-may-support-cognition-in-sleep-deprivation-study/   https://pmc.ncbi.nlm.nih.gov/articles/PMC10902318/   https://medicalxpress.com/news/2024-04-creatine-cognitive-deprivation.html       Your Gum Is Dosing You With Thousands of Microplastics   A pilot study tested 10 commercial gums ... five synthetic, five marketed as natural or plastic-free ... and found every single one shed hundreds to roughly 3,000 microplastic fragments per stick into saliva, with no meaningful difference between synthetic and "natural" varieties. Host Dave Asprey connects this to total toxic load management, explains why "natural" label claims mean nothing without polymer-free verification, and makes the case that even innocent daily habits contribute to the cumulative plastic burden most people aren't tracking.
