There's no definitive answer to how long humans can live. While some researchers believe there's a natural limit around 120, 140, or 150 years, others argue that aging doesn't necessarily lead to death and that there might not be a limit at all.
This debate stems from the fact that life expectancy has steadily increased over the centuries, more than doubling in the last two hundred years. The record for the maximum human lifespan has remained unbroken since the 1990s, but scientists are exploring new ways to potentially extend that record.
It's fascinating to consider that if we could eliminate aging at the cellular level, humans could theoretically live for a millennium or even 20,000 years! While this is a far-fetched possibility, it highlights the ongoing research into aging and its potential for extending human lifespans.
In summary, there's no fixed answer to how long humans can live. While a natural limit might exist, ongoing research suggests that it could be pushed further than previously thought.
