Have you ever wondered that you might be ageing really fast that your body is 50 years older than you? Yes, that's a real things. There also exists a flip side since there are people who are growing so slow that they are biologically in their 20s.
A new research tried to shed more light on biological age and chronological age.
Some researchers involved 4,000 people in their experiments and compared their biological ages with the number of birthdays they have celebrated so far, according to an Express report.
According to a The Telegraph report, the researchers looked into the DNA of these 4,000 people over the age of 57. The results were remarkable - one 66-year-old person was found to have a biological age of 114 while another 59-year-old person was physically just 23.
The report mentioned what researchers looked into - the epigenetic changed; the DNA alterations that turn genes on or off. The DNA undergoes a turmoil, a kind of disarrangement, over the period of time.
"Some people who are 57 or older look like they're in their 20s, while some people look like they're over 100, and there's a big range in between.
"We think that adverse social experiences can change your epigenetic profile in ways that may subsequently influence your health adversely.
"There were people who looked 36 years younger, while some look 48 years older," Express was quoted researcher Dr Eileen Crimmins, professor of gerontology at the University of Southern California, as saying.
In the research it was found that women had naturally biological ages one or two years younger than men. Obesity was one of the biggest factors to cause internal ageing with smoking and childhood issues too playing a significant role in internal ageing.
We don't age at the same rate, conclusions of the research suggested. Our experiences throughout our lives contribute negatively or positively when it comes to ageing.
So choose wisely how you want to age because you can be chronologically old but at heart, you can be "forever young" as chronologically old musician Bob Dylan once said.
