Researchers have long pondered the idea of living forever, with countless songs, books, and poems dedicated to the subject. Recently, a group of scientists set out to determine the maximum age a human can live to if free of illnesses and diseases. Their research, utilizing a dynamic organism state indicator (DOSI), revealed that the human body can potentially live between 120 and 150 years. As we age, our ability to recover declines, directly impacting our longevity. By understanding this limit, researchers hope to develop new anti-aging interventions to help people not only live longer but also healthier lives. This groundbreaking research sheds light on the aging process and presents opportunities for enhancing quality of life as individuals age. Although the pursuit of extended longevity raises ethical and societal considerations, the ultimate goal is to help individuals enjoy healthier, happier lives well into their later years.
