The study authors noted that, “The death rate significantly increased as biological age became larger than chronological age.” The authors concluded, “Biological age could be used to predict future risk of death.”Īnother study found a link between high biological age and breast cancer. In fact, biological age has been shown to accurately predict longevity and mortality rates. They also experienced worse symptoms, up to and including death. Patients with a high biological age were more likely to contract COVID-19. A recent study of COVID-19 patients found that COVID-19 severity is predicted by earlier evidence of accelerated aging. A 40 year old with a biological age of 60 can expect to experience the same age-related diseases and impairments of someone 20 years their senior. Over time, it becomes almost certain that some cells will break down or mutate in ways that are dangerous to us.Ī high biological age indicates that this process has been accelerated, increasing the chances of dangerous mutations earlier in our lives. Each time a reaction occurs, it has a chance of going wrong. Our bodies are incredible machines, and they perform millions of chemical reactions each day. The process our bodies undertake at a cellular level play an important role in how well we age, and what diseases are likely to affect us. What are the risks of having a high biological age? Equally if you’re a 25 year old who smokes two packs a day, doesn’t exercise, and eats a high fat diet, you might have a biological age of a 40 year old. For example if you’re 50 years old but you’re fit and healthy, you might have a biological of 35. Your biological age refers to how fast your body has aged at a cellular level, relative to a chronological baseline. Why are some people fit and healthy into their eighties and nineties, when others show signs of old-age when barely past middle age? Gerontologists (people who study the aging process) have long believed that chronological age isn’t the only risk factor we need to consider. While chronological age is the primary factor associated with many conditions, it doesn’t tell the whole story. Chronological age plays an important role in how our bodies respond to stressors and diseases. For example you’re likely to lose some hearing or eyesight as you get older, and most cancers are considered age-related diseases. Chronological age is the primary risk factor associated with age-related diseases and impairments. Your chronological age is the number of years you’ve been alive. Here’s everything you need to know about how old your body is, and what you can do to keep it younger and healthier for longer. That’s because our biological age (the rate at which our bodies show signs of aging) can be completely different to our chronological age.
