Humans have no maximum lifespan, suggests a new study published in Nature.
No Age Limit!
So, apparently, humans can live till however long they can live—there is no age limit to their lifespan. While we all have an ‘expiry date’, the human race itself does not have a maximum number of years, says the new study. The average life expectancy in recent years is at around 65. Then, we have some rare humans who live till beyond 110. Can humans live for longer than this? A question that has fascinated scientists for long now.
For how long is it possible for humans to live?
Noone Has Reached Maximum Age?
While we all shall taste death, the researchers behind the findings, a team from McGill University, explain that they have found no evidence showing that maximum lifespan has reached a halt. This conclusion is based on an evaluation of the lifespans of the longest-living people (since 1968) from several countries like France, Japan, the UK, and the US. According to the biologists, no limit was found to ageing. Even if there is a maximum, it has not been reached or identified.
While the maximum remains unknown, it might actually be increasing, suggests one of the study authors, Siegfried Hekimi.
“We just don’t know what the age limit might be. In fact, by extending trend lines, we can show that maximum and average lifespans, could continue to increase far into the foreseeable future,” says Hekimi.
Increasing Lifespans, A Trend
Average lifespans have been increasing, according to scientific findings. For instance, the mean lifespan of Canadians back in 1920 was at 60 years, and this increased to 76 years in 1980, ultimately reaching 82 years (the current figure). This increasing trend might extend to the maximum lifespan as well.
Perhaps, the unknown upper limit can be further increased with technological advancement and medical improvements? Hekimi says that it is not possible to forecast the future human lifespans; it would be difficult to guess.
“Three hundred years ago, many people lived only short lives. If we would have told them that one day most humans might live up to 100, they would have said we were crazy,” says Hekimi.
Can we live for centuries on end? Can a human live for a thousand years? This might sound far-fetched, but the researchers of the new findings saying that they have found no age limits does broaden the horizons, right? The Qur’an and the Bible describe prophet Noah as having lived for 950 years. The human mind does covet the idea of having a really, really long life. Maybe, it’s not all that impossible?
