Mumbai, Nov 12: A recent study into the molecular biology of aging suggests that human aging is not always gradual; instead, it occurs in two sharp bursts—around age 44 and again near age 60. Researchers tracking 108 adults over several years found that these abrupt changes affect a wide range of biomolecules, including RNA, proteins, lipids, and microbiome taxa from the gut, skin, nasal, and oral regions.

Geneticist Michael Snyder of Stanford University explained that these two peaks represent dramatic molecular shifts rather than steady progression. The mid-40s surge primarily involves changes linked to lipid, caffeine, and alcohol metabolism, cardiovascular health, and skin and muscle function. The early 60s peak is associated with carbohydrate and c
