Gut microbes may dictate cellular aging, new review suggests
A Frontiers in Aging review introduces the microbiome‑gerogene axis, proposing that gut microbes act as upstream regulators of cellular aging networks. Age‑related dysbiosis reduces key metabolites, leading to leaky gut, chronic inflammation and epigenetic drift that accelerate organ decline. The authors highlight precision interventions such as ellagitannin‑derived urolithin A and fermentable fibers to restore microbial balance.
Your Spine Shrinks 2cm Every Workday
People lose up to 2 cm of height each workday as spinal discs compress from prolonged sitting. A Dublin product manager measured a 1.8 cm drop by 6 pm, confirming research that the average daily loss is about 19 mm. Traditional stretches like cobra or mountain pose provide only temporary relief because they don’t first decompress the spine. The post outlines a three‑step sequence—passive hanging, thoracic extension, then posterior‑chain activation—that can restore height within 30 days.
