When coffee doesn’t overlap with sleep, it may support longevity by: + Boosting metabolic rate (calorie-restriction mimetic) + Inducing autophagy (esp. during fasting) + Improving vascular function & blood flow + Anti-inflammatory & neuroprotective effects This is due to the caffeine + polyphenols (chlorogenic and caffeic acids).
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
