Scientists have discovered that when men lose their Y chromosome with age, it's not just a harmless hiccup - it could be driving serious diseases like heart problems and Alzheimer's. Think of it like losing a key player from your cellular team. What's wild is that these Y-less cells might actually grow faster than normal ones, potentially causing chaos in our bodies as we age.
