With a simple blood test, we will know when we will die.

American startup Life Epigenetics is breaking new ground in healthcare by estimating a person's biological age and life expectancy with a simple blood test. However, this revolutionary technology also raises serious ethical and societal questions about issues like insurance discrimination and data privacy.

At the heart of this technology lies the science of epigenetics, which examines how our genetic heritage interacts with our lifestyle. The test, developed by Life Epigenetics, analyzes not DNA sequence but the effects of lifestyle factors (diet, stress, exercise, etc.) on gene expression. A sophisticated algorithm determines a person's "epigenetic age," which can differ from their chronological age—their true biological age. This finding could allow individuals to consciously change their habits to extend their lifespan.

The technology's first and most controversial application is insurance. Life Epigenetics, a subsidiary of the insurance company GWG, aims to use these tests to reshape the life insurance market. Under the plan, individuals with a healthier, "younger" biological age would be offered lower premiums, while those with an older epigenetic age would be charged higher premiums. While this approach has the potential to promote healthy living, it raises an important question: Will it create a new form of discrimination?

It can detect symptoms years before they appear.

Epigenetic testing poses a new danger, one that could be called "biological discrimination." There are concerns that the system will penalize those at a genetic or socioeconomic disadvantage. Furthermore, who will ensure that this highly personal data is not used for commercial purposes and that its confidentiality is maintained? Another critical risk is that inequitable access to testing will exacerbate existing health disparities.

Despite all its risks, the potential of epigenetics in medicine is immense. Experts say these tests could identify predispositions to chronic diseases years before symptoms appear. This could allow for the development of preventive medicine and personalized health advice tailored to each individual's epigenetic profile. This could revolutionize our understanding of health, shifting from reacting to illness to actively preventing it.

The test developed by Life Epigenetics promises humanity the power to understand and shape its own biological destiny. However, utilizing this power in a fair, equitable manner that respects individual rights will be the most crucial test we must face as a society. How we manage technological progress without compromising human values ​​remains one of the most fundamental questions of the future.
