Centenarians

centenarians

Centenarians are people who have reached the age of 100 years or more. They represent a small but growing group in many countries as life expectancy rises. Scientists and health professionals study them to learn how some people live long lives with relatively good function. Studying centenarians helps reveal the roles of genetics, lifestyle, diet, and social connections in healthy aging. Many centenarians show differences in how their bodies handle stress, inflammation, and disease. Knowing about centenarians matters because their lives can point to ways to improve health for everyone as populations get older. Insights from these older people can inform public health policies, medical care, and community design to support independence and quality of life. There are also social and economic effects, such as planning for retirement systems and caregiving resources. While reaching 100 is not a goal for everyone, learning from centenarians can help reduce chronic illness and increase the years people stay active. Their stories also challenge assumptions about aging and show that long life can still include meaning and purpose.
