DNA analysis shows that a 60-year-old person can have a genetic age of more than 100

New study identifies how DNA is ‘switched on and off’, leaving some ‘super-agers’ in their 60s with a physical age of DECADES younger while others age so fast that their bodies are in their 100s

  • According to experts from the University of Southern California, some people are aging so much that their bodies are more than 40 years older than their actual age
  • In one example, researchers discovered that a 66-year-old had a biological age of 114, while another 59-year-old was 23
  • Things like smoking, stress, pollution or obesity along with ‘epigenetic changes’ can be used as a clock to determine how quickly a person gets older
  • Epigenetic changes can help determine whether genes are switched on or off and can influence the production of proteins in certain cells

Researchers in California have revealed that a person who is 60 years old can have a genetic age that is older than 100 or as low as 20.

The research was conducted at the University of Southern California and looked at the degree of change that occurred in the DNA of more than 4,000 people over the age of 57.

According to university experts, some people are getting so much older that their bodies are more than 40 years older than their actual age.

Meanwhile, people in their 60s, known as ‘super-agers’, have a physical age that is decades younger.

Dr. Eileen Crimmins, professor of gerontology at USC, said to Express: “Some people aged 57 or over look like they are in their twenties, while some people look like they are over 100, and there is a wide range in between.”

Crimmins said experts believe that “unfavorable social experiences can change your epigenetic profile in a way that can subsequently affect your health.”

“There were people who looked 36 years younger, while some looked 48 years older,” she added.

In another example, researchers discovered that a 66-year-old turned out to have a biological age of 114, while another 59-year-old was 23, also known as a ‘super-ager’.

Researchers looked at epigenetic changes for the study. Epigenetics are chemical compounds that are added to individual genes that can regulate their activity.

Epigenetic changes can help determine if genes are switched on or off and can affect the production of proteins in certain cells, producing only necessary proteins, according to the US National Library of Medicine.

Crimmins said, “People believe that the underlying aging process is one that underlies all the different health outcomes related to age, such as cognitive decline, illness, disability, vulnerability, and mortality.”

Scientists used blood samples from research participants and tested them against “epigenetic clocks” to measure DNA changes, according to Express.

Things like smoking, stress, pollution or obesity, along with the ‘epigenetic changes’ can be used as a clock to determine how quickly a person gets older.

Crimmins said experts discovered that being a woman delayed the aging clock for up to two years, while obesity accelerated for up to 18 months.
