The search for youth in an ageing world

(Level B2 and above) – Longevity biotech, idioms and phrases related to age.

At 67, Dr Tyger is no spring chicken. In fact, he is starting to show signs of age. He has quite a few senior moments too, like losing his lab coat or losing both his keys and glasses last week. But he refuses to act his age – he still goes paragliding and mountain climbing for example. His dynamism shows that age is just a number. In fact, he plans on living healthily to a ripe old age. That’s why he runs longevity biotech research projects.

Biotechnology is the use of bacteria and plant and animal cells for industrial or scientific purposes, for example, to make drugs or chemicals.

Even if life expectancy has increased around the world, good health expectancy has increased at a slower rate. So, we live longer, but not necessarily healthier. It is indeed a mixed blessing.

The typical diseases of old age nowadays are cancer, heart disease, diabetes and senility. And old age is what longevity biotech wants to tackle.

Some people, including scientists, think we should classify ageing as a disease. But old age is not a disease, it is the natural outcome of a long life.


The difference between biological age and chronological age


As many people now live into their 90s and beyond without chronic illness, longevity biotech wants to discover what differentiates these healthy agers and translate these findings into medicine.

Today, the sector is estimated to be worth $26.5 trillion; it involves over 50,000 companies, more than 10,000 investors and over 1,000 research and development (R&D) centres.

For example, Alto Labs in the US is working on technology that can reprogram cells to rejuvenate and potentially prolong human life. Insilico Medicine in Hong Kong uses artificial intelligence and deep learning technology to identify molecules to treat various cancers. Acorn Biolabs in Canada provides cell preservation services for non-invasive cell freezing that can be used for future medical applications. Juvenescence in Ireland develops therapies that allow patients to slow or reverse ageing. Many studies are published, including a recent one in mice, that shows that transplanting certain healthy gut microbiota (bacteria that live in the intestines) can reverse ageing. And there is a new Longevity Biotechnology Association which represents geroscience and gero-therapeutics (the development of new medicines and therapies to prevent and cure, rather than merely manage, the health conditions of late life).


Should age – and time itself – be challenged? Or just managed?


Addressing the gap between health span and lifespan is essential for long-term global economic prosperity, says Kristen Fortney, CEO of BioAge Labs, a clinical-stage company. Furthermore, “older people have a fundamental right to live healthy, full lives, and to have their medical conditions taken seriously as targets deserving of clinical interventions, rather than simply dismissed as inevitable consequences of ageing.”

As the world of humans is getting older, this is a timely topic which raises many questions. Should age – and time itself – be challenged? Or just managed?

Is this the medical version of the fountain of youth or the elixir of life?

Will better health help overcome what many people of a certain age suffer from, ageism?

Will longevity cures be reserved for richer people?

Finally, if we do find cures for age-related diseases, what will old people die off?

Dr Tyger certainly thinks about those questions when he is not working on his cell regeneration project.

Age-related idioms and phrases

  • No spring chicken: usually used in negative contexts to say someone is no longer young. A spring chicken is a young person.
  • Senior moment: an occasion when someone forgets something – Is this just a senior moment or am I losing my memory? I can’t remember where I parked the car.

  • Age is just a number: no matter how old we are, we can do anything. Yuichiro Miuro climbed Mount Everest when he was 80 years old. This shows that age is just a number.
