<a target="_blank" href="https://www.buzzsprout.com/twilio/text_messages/413041/open_sms">Send us a text</a>Coffee may nudge biology, but only within limits. We dig into new research suggesting that three to four cups a day align with longer telomeres for people with severe mental illness, then challenge the hype with the caveats that matter: observational design, smoking as a confounder, wildly different cup sizes and brew methods, and the reality that more caffeine can erase potential benefits. We translate the science into practical guidance—why moderation beats megadoses, how 400 mg per day became a sensible upper bound, and where sleep and stress fit into the bigger picture of healthy aging. Then we pivot to a feline mystery that spans millennia. Long before house cats padded through Chinese homes, leopard cats were the stealthy mousers around early settlements, drawn by grain and the rodents it attracts. Using mitochondrial DNA from ancient remains—paired with clues from art—we trace the species shift around the eighth century as domestic cats, descended from the African wildcat, traveled the Silk Road and found their place beside people. Tameness, tolerance, and a knack for living close to humans helped them outcompete their wild cousins in a world reshaped by trade and urban life. Across both stories runs one thread: human routines create niches that biology rushes to fill. Our cups change our days at a cellular level, and our granaries and roads alter which animals share our spaces. If you love clear science, a bit of myth-busting, and the unexpected link between breakfast and ancient history, you’ll feel right at home here.
