Get this: researchers just discovered that tweaking the 'scaffolding' around heart cells (the extracellular matrix) could actually slow down or even reverse heart aging. They built a wild new model that lets them see how a young vs. old environment affects heart cells, and it turns out the chemical signals matter more than stiffness! Human treatments are still a ways off, but in the meantime, regular exercise, a healthy diet, good sleep, less stress, and cutting back on booze are your best bets for a younger heart. #HeartHealth #Aging #ScienceNews #Health
