### Researchers Create Cheek Swab Test to Forecast Lifespan

Picture having the ability to forecast the duration of your life with merely a cheek swab. With recent strides in the realm of biological aging research, this seemingly futuristic notion could soon turn into reality. A recent publication in *Frontiers in Aging* illustrates that researchers have crafted a method that can evaluate your biological age—and potentially foresee your lifespan—by examining cells gathered from the inside of your cheek.

#### The Science Behind CheekAge

The investigation focuses on a method named **CheekAge**, which belongs to a new category of epigenetic clocks. These clocks are designed to assess biological age by scrutinizing modifications in gene expression as time progresses. In contrast to your chronological age (the total years you’ve lived), your biological age indicates how old your body genuinely is based on cellular and molecular indicators.

CheekAge operates by examining particular DNA markers found in cheek cells. These markers assist scientists in gauging how your body ages on a biological level. The premise is that different regions of your body—such as your blood, skin, or cheek cells—can provide distinct perspectives on your overall health and aging trajectory.

#### Evaluating the Tool

To authenticate the CheekAge method, researchers gathered blood samples from more than 1,500 subjects ranging in age from 67 to 90. Although the samples lacked all the DNA markers that CheekAge is intended to analyze, the method still demonstrated a robust capacity to assess mortality risk. In essence, even with partial data, CheekAge could predict how much longer individuals might survive based on their biological age.

The research indicated that participants with the most advanced biological age markers faced a 50% mortality rate roughly 7.8 years earlier than those with younger biological markers. This implies that CheekAge may surpass other current epigenetic clocks in lifespan prediction accuracy.

#### The Rationale for Cheek Cells

Cheek cells are perfectly suited for this type of testing because they can be easily accessed and collected non-invasively. A simple swab inside the mouth is sufficient to obtain the necessary cells for analysis. This renders the test not only convenient but also more cost-effective and accessible compared to other approaches that necessitate blood samples or more invasive methods.

#### Prospective Implications

While CheekAge is still in the preliminary stages, the method possesses considerable potential for the future of medical care. Once fully realized, it could furnish healthcare providers with a novel approach to evaluate a patient’s biological age and general health. This could prove especially beneficial in preventive healthcare, enabling physicians to customize treatments and lifestyle advice depending on an individual’s biological aging pace.

Additionally, due to the test’s simplicity and non-invasive nature, it could motivate more individuals to undergo testing, resulting in earlier interventions and potentially lengthening lifespans.

#### Advancing Understanding of Aging

The creation of tools such as CheekAge is part of a larger scientific effort to comprehend the biological clocks that regulate aging in both humans and animals. For instance, certain creatures, like axolotls, have exhibited the capability to halt their biological clocks, a curiosity that has captivated scientists investigating aging and longevity. In a similar vein, researchers are delving into anti-aging medications that have shown initial success in prolonging the life of mice.

Although we are still a distance away from being able to halt or reverse human aging, tools like CheekAge bring us closer to unraveling the intricate mechanisms underlying biological aging. And perhaps in the future, a quick cheek swab may not only reveal your biological age but also provide guidance on how to lead a longer, healthier existence.

#### Conclusion

The CheekAge method signifies a remarkable advancement in the field of aging research. By evaluating biological markers within cheek cells, researchers can estimate an individual’s biological age and accurately predict their mortality risk. Although still in development, this method has the potential to transform our approach to aging and healthcare, providing a non-invasive, cost-effective means to assess and enhance our health as we age.

As research progresses, the aspiration to predict—and possibly even lengthen—our lifespans may soon become a tangible goal.
