Maximum Lifespan

Maximum lifespan refers to the longest period that a human or any species has been observed to live under ideal circumstances. For humans, this is currently around 120 years. It represents the upper limit of potential longevity, shaped by biological factors like genetics, cellular aging, and health, as well as environmental influences. While many live well into their 80s or 90s, maximum lifespan is about the ceiling beyond which no one has been documented to survive, highlighting the natural limits of biological aging.
