What people living up to 100 have in common, according to science

Living to see 100 is an important feat that has a common thread.
Recent centenary studies, people who are 100 years old, have found that they suffer from less diseases in general, develop them more slowly and are less likely to experience fatal conditions compared to people who live shorter lives.
A 2024 study by Sweden, published in the Journal Gerhatience, considered historical data of people over 60 years old between 1912 and 1922.

The researchers followed these individuals from 1972 to 2022, considering the age of their death and also medical complications such as stroke, myocardial infarction, hip fracture and various types of cancer.
It was discovered that centenarians had a lower age of life for all conditions, except hip fractures, suggesting that 100 -year -old children can delay and avoid many important diseases related to age instead of surviving them.

The findings challenge the idea that a longer life inevitably leads to higher disease rates, the researchers declared.
Another study in August 2025, conducted by the same researchers and published in the Lancet, analyzed how older people accumulate and manage health conditions throughout a useful life, instead of avoiding them.

The researchers tracked the health of the participants born between 1920 and 1922, comparing the trajectories of the centenary disease with those who did not live so much.
It was discovered that the 100 years or more have less diagnosed conditions and also accumulated diseases at a slower speed.

The researchers found that cardiovascular diseases were the most common diagnoses at all ages, but contributed less to the general load of the disease among those that reached 100.
Malignant neoplasms, such as cancer cells that are generally spread, were more present in centenarians, while neuropsychiatric conditions, such as anxiety and dementia disorders, were less common.

It was also discovered that 100 -year -old people had less diseases that occurred at the same time and were more likely to have confined conditions to a single group of diseases.
“Future research should aim to identify genetic, epigenetic and environmental factors that underlie these patterns to inform preventive strategies of early life that promote longevity and resilience,” said the researchers.

What distinguishes centenarians
Dr. Macie P. Smith, a social and gerontologist with a license based in South Carolina, said it makes “full sense” that people who avoid serious diseases such as stroke and heart disease live more than 100 years.
People who have reached 100 are considered “traditionalists”, which have generally avoided exposure to harmful elements such as radiation, additives, preservatives and artificial coloring in food, Smith told News Digital.

“They were not exposed to a large amount of modern medicine,” he said. “They trusted natural remedies and organic foods.”
Modern technology and global connections, which were not available for centenarians, could also contribute to stress and other mental health factors, according to Smith.

“They had the ability to deal with their own matters while reducing their stress levels,” he said. “That only brings a longer life … when you care about other people’s business, you assume other people’s problems, thus increasing stress levels. This is called indirect trauma.”
Smith also believes that the previous generation is more “free of free spirit.”

“They did not assume the restrictions we take today to look in a certain way or be in a certain way in public,” he said. “There was much less scrutiny in those days.”
“Yes, they had their struggles that we don’t see today; however, they simply appeared in a different way, and they were handled in a different way.”

Adopting a healthy lifestyle will now help avoid health complications later, a doctor said. (Istock)
Choosing your path when you are younger will determine how you live when you are old, said Smith, either independently or dependent, or living on your own or in a community.
Making healthy lifestyle decisions from the beginning can also significantly reduce the risk of complications in the future, which can affect longevity.

Smith recommends eating a low fat diet, low salt and healthy for the brain and eliminating processed foods, while handling stress, interacting with family and friends, staying active and sleeping properly.
“This will prolong life and improve the quality of life,” he said.
