Now we can potentially live forever, should we?

Earlier this year, I had the pleasure of delivering an RSJ assembly entitled Lessons Learnt from History. Rather than focusing on a historical event or individual, I explored the story of the Human Genome Project and one of its greatest legacies: the decision to make the human genome freely available to scientists around the world. It was a reminder that some of humanity’s greatest breakthroughs have come not from protecting knowledge, but from sharing it.

Advances in genetics and our growing understanding of ageing mean that scientists are now beginning to ask a question that once belonged solely to the pages of science fiction. If it became possible to extend human life dramatically—perhaps even indefinitely—should we?
Ask a group of people whether they would like to live forever and you’ll probably hear two very different answers. Some would embrace the idea without hesitation. Others would wonder whether an endless life might eventually become more of a burden than a blessing.
Both reactions are understandable. Death is the one certainty every human shares, yet it is also something we have spent centuries trying to delay. Modern medicine has transformed diseases that once claimed millions of lives into manageable conditions, and average life expectancy has more than doubled in many parts of the world over the past two centuries. Living forever may sound like science fiction, but scientists are beginning to ask whether ageing itself should be viewed differently.

One of the leading researchers in this field is Harvard geneticist Dr David Sinclair. Rather than treating ageing as an unavoidable part of life, Sinclair argues that it should be considered a medical condition that can potentially be slowed or even treated. His research explores why our cells deteriorate over time and whether repairing this damage could allow people to remain healthier for longer. While many of his ideas remain the subject of scientific debate, and much of the research has yet to be proven in humans, it raises a fascinating possibility: what if growing old is not inevitable in the way we have always assumed?

For many people, the appeal is obvious. More healthy years would mean more opportunities to learn, travel and build relationships. Imagine mastering a musical instrument over fifty years, becoming fluent in several languages or changing careers multiple times without feeling that time is running out. It would certainly be music to the ears of both the Music and EAL departments, although it might also mean staying at RSJ for a little longer than expected.

Longer lives could also transform families. One of life’s greatest hardships is losing the people we love. If ageing could be delayed significantly, grandparents might spend decades watching future generations grow up. Family history would be carried not just through photographs and stories, but through living memories spanning generations.

Yet every scientific breakthrough brings new questions.

If people lived dramatically longer, where would everyone live? Our planet already faces challenges with housing, food production and energy consumption. A society in which people rarely died would place enormous pressure on resources and force governments to rethink almost every aspect of how communities function.

The world of work would also look very different. Careers rely on the expectation that people eventually retire, creating opportunities for younger generations. If leaders, scientists or business owners remained in their roles for hundreds of years, would innovation slow? Experience is invaluable, but history also shows that progress often comes from younger generations questioning established ways of thinking.

Perhaps the biggest question, however, has nothing to do with biology.Many of the moments we value most are meaningful because they are temporary. School eventually ends. Holidays come to a close. Even spending time with friends feels special because we know those moments cannot last forever. Deadlines encourage us to revise, complete coursework and make the most of the time available. Without an ending, would we still feel the same sense of purpose, or would there always be another tomorrow?

Research into ageing is advancing at an extraordinary pace, and scientists such as Dr David Sinclair continue to challenge long-held assumptions about what growing old really means. Whether or not humans ever achieve dramatically longer lifespans, these discoveries encourage us to think differently about health, medicine and the future of our species.

Perhaps the value of life has never depended on how long it lasts, but on how we choose to spend the time we have. Scientific discovery gives us remarkable new possibilities, but it cannot tell us how they should be used. Those decisions belong not only to scientists, but to all of us.
