Can humans live permanently or is there a biological expiration date? In this Freaky Science documentary, we check out the 120-year human life-span limitation and the shocking science of aging that suggests our bodies have an integrated "kill-switch." From the Hayflick Limitation discovered in the 1960s to the most recent 2025 longevity research study on partial reprogramming and senolytics, we uncover why the human ceiling sits at 120 years and what occurs when we try to cheat the clock.
TL; DR: Science has actually determined a difficult stop for human life near 120 years. This video breaks down the cellular countdown (telomeres), the evolutionary compromise known as Antagonistic Pleiotropy, and the "zombie cells" that trigger decline. We likewise take a look at nature's outliers like the Bowhead Whale and Naked Mole Rat to see if their "longevity cheats" can be applied to human beings through CRISPR and Yamanaka Aspects.
