The Science of Aging: From Epigenetics to Vaccination
Research has confirmed that some people age faster than others, with biological age referring to how old a person seems, while chronological age is the number of years a person has been alive. A study of approximately 1,000 men and women born between April 1972 and March 1973 examined biological age in comparison to chronological age, using 18 biological markers to assess the biological age of each participant. The study found that some people were aging at a rate of up to three years per year, while others were aging at a rate closer to zero years per year. The goal of the study was to identify ways to spot signs of aging early in life to prevent the onset of age-related disease.
