How Old Are You, Exactly?

The Aging Disparity


Why do some people not seem to age, ever? As I wondered about the curious phenomenon of age-defying individuals like celebrities and biohackers, it became clear that the passage of time is not always an accurate indicator of a person’s health.

Indeed, each person’s aging process is unique due to many factors that co-influence our pace of reaching the later stages of life. While most people appear age-appropriate, some look younger (or older) than their chronological age, as indicated in their IDs.

You’re right.

Biological age can vary significantly from chronological age. In other words, they do not always align with each other.


The Aging Factors

Lifestyle choices are vital, with factors such as diet, exercise, and stress management affecting the body’s cellular and overall health. Regular physical activity can keep our heart robust, muscles strong, and joints agile, contributing to increased longevity.

A well-balanced diet rich in nutrients can combat oxidative stress and inflammation, both associated with aging. Meanwhile, stress management techniques like meditation can reduce the impact of psychological stress, which can otherwise accelerate aging.

Of course, genetics play a significant role in how we age.

Some individuals may have inherited advantageous genetic variations that protect against age-related diseases and slow aging. In contrast, genetic predispositions can make some more susceptible to premature aging or age-related conditions.


What Is a Biological Age Test?

A ‘Real Age’ Test

Fortunately, in the pursuit of extending human life expectancy, numerous research labs have been diligently developing tools to determine how we age from within – the biological age test, also known as the real age test.

This cutting-edge assessment goes beyond chronological age and delves into the intricate molecular processes that shape our aging trajectory.

One of the most crucial factors influencing our aging is gene expression, which refers to how our genes are activated or silenced in response to internal and external stimuli.

Over time, environmental factors, lifestyle choices, and other influences can lead to alterations in gene expression, impacting the overall aging process.


Epigenetic Clocks

Two significant measures (known as epigenetic clocks) that have gained relevance in biological age testing are PhenoAge and GrimAge:

  • PhenoAge: evaluates a comprehensive set of aging-related biomarkers to estimate an individual’s biological age accurately. This sophisticated assessment considers various blood-based markers, including C-reactive protein, albumin, and hemoglobin, to provide insights into overall health and aging status.
  • GrimAge: goes further by incorporating DNA methylation patterns into its analysis. DNA methylation is an epigenetic modification that influences gene expression. GrimAge utilizes these patterns to assess an individual’s risk of age-related diseases, providing a bigger picture of their biological age.


How Does a Biological Age Test Work?

Testing Procedure


A typical procedure involves the user providing a sample of their biological material, either a saliva or blood sample, which contains essential genetic information that allows experts to analyze epigenetic modifications through gene expression patterns.

Once the sample is collected, it undergoes a comprehensive analysis. The data is then compared to a vast reference database of biological age markers. This comparison allows experts to estimate the individual’s biological age accurately.

The results can be presented as a numerical value or through a graphical representation, illustrating how the biological age compares to the traditional chronological age.

The final report generated from the test includes the person’s biological age and may offer personalized recommendations to promote healthy aging. These often revolve around lifestyle changes that can positively impact gene expression and aging.


Some Popular Tests

One example of biological age tests is the myDNAge test kit, built upon Dr. Steve Horvath’s epigenetic clock.

Based on cutting-edge Next-Generation Sequencing Technology, the test scans over 2,000 biomarkers in the human genome, susceptible to epigenetic changes. By analyzing these markers, it accurately calculates an individual’s biological age.

Some other biological age tests that are currently available include the following:


What Does a Biological Age Test Result Mean to You?

More Than a Number

The significance of a biological age test extends far beyond simply informing individuals of a number representing their actual age.

It is a powerful tool enabling experts to map out a comprehensive action plan, addressing various aspects of a person’s health to optimize well-being and increase lifespan.

For instance, the myDNAge test report goes beyond revealing biological age and offers a tailored improvement plan. This plan incorporates beneficial practices related to nutrition, lifestyle modifications, stress and weight management, and physical activity.


Proactive Measures

By implementing the recommendations provided by the myDNAge test report, individuals can proactively address health concerns and change their daily routines.

Moreover, the biological age test report highlights specific biomarkers for overall health. Understanding the status of these biomarkers empowers individuals to take targeted actions to maintain them at optimal levels.


What Can Affect Your Biological Age Test Result?


Various factors can negatively influence a person’s biological age test result. Understanding these elements is crucial to make informed decisions about health and well-being.

Factors negatively affecting a biological age test result include the following:

  • Sedentary Lifestyle: Lack of physical activity accelerates aging processes and raises biological age.
  • Poor Diet: Unhealthy eating habits, high in processed foods and sugars, contribute to premature aging.
  • Chronic Stress: Prolonged stress increases inflammation and negatively affects cellular health, leading to an older biological age.
  • Sleep Deprivation: Insufficient sleep disrupts bodily functions, contributing to an older biological age.
  • Obesity: Excess weight can strain organs, leading to age-related health issues and an elevated biological age.
  • Smoking: Tobacco use accelerates cellular damage, increasing biological age.
  • Excessive Alcohol Consumption: Heavy drinking harms organs and promotes aging, impacting biological age negatively.


Real-life Success Stories Through Biological Age Testing
