Caspi, Yashin, Moffitt, Sugden and colleagues find 38 year olds vary in biological age from 28 to 61
"Some people age faster than others" - Boston Globe. 7/17/2015.
This study explored what aging looks like in the third and fourth decades of life, using data from 952 study participants born in Dunedin, New Zealand in 1972-73. At ages 26, 32 and 38, respondents were measured on 18 biomarkers reflecting metabolic and immune function, the state of their gums, hearts, lungs, blood vessels, kidneys and livers, BMI, and telomere length. Researchers found that the biological age range for the 38 year olds was 28 to 61, with the more aged respondents showing greater IQ declines, increased risk of stroke, and worse balance, fine-motor control, and grip strength. They were also more likely to report poor health.
