That headline is too broad. Many people live well beyond 80, and life expectancy varies substantially by country, sex, genetics, socioeconomic circumstances, and health behaviors.
If the article is discussing why some older adults don’t reach their 80s or live much beyond them, four major factors commonly discussed are:
-
Cardiovascular disease — heart disease and stroke remain major causes of death in older adults. High blood pressure, smoking, diabetes, and high cholesterol increase risk.
-
Cancer — cancer risk generally increases with age, although prevention and early detection can reduce the risk of dying from some cancers.
-
Frailty and falls — loss of muscle strength, balance, and physical resilience can make infections, falls, fractures, and other illnesses more dangerous.
-
Chronic diseases and infections — conditions affecting the lungs, kidneys, liver, and other organs can accumulate with age, while an older person’s ability to recover from serious infections can decrease.
Importantly, turning 80 isn’t a biological “cutoff.” Reaching older age is influenced by many interacting factors, and there are large numbers of people who remain healthy into their 80s, 90s, and beyond
