''Why Do We Die?'' | The Shocking Truth Evolution Doesn't Want You to Know

A Greenland shark can live for centuries—estimated around ~400 years in published research—while humans struggle to reach 90. Why? Because aging isn’t just “wear and tear.” It’s a biological program—a tradeoff evolution accepted to protect you early in life (especially from cancer), even if it costs you later. In this video, we break down the real mechanics of aging: telomeres and the Hayflick limit, why telomerase (the “reset enzyme”) is mostly switched off in adult tissues, how mitochondria (your ancient cellular power plants) contribute to damage, and why senescent “zombie cells” poison the body through chronic inflammation. We also explore “exceptions” like the immortal jellyfish and evidence of high telomerase activity in species like lobsters—then ask the real question: if biology can do it, why didn’t evolution give it to us?
