In the quest for a longer and healthier life, the concept of aging is at the forefront of scientific and medical exploration. Traditionally, discussions around aging have been confined to a singular metric – chronological age. However, the landscape is rapidly evolving with the advent of precision health technologies that delve into multiple dimensions of the aging process. Among these, the notion of PrecisionAge stands out as a revolutionary approach, offering insights into cognitive, functional, anatomical, epigenetic, hormonal, fitness, microbiomic, genomic, and bio-aging ages. By incorporating bio-based markers and cutting-edge technology, the BioAro model seeks to redefine our understanding of aging, moving beyond just the passage of time to a more holistic view of health and vitality.
