(Keep in mind that all of the participants were the same age chronologically!) And in case you need even more convincing to take better care of yourself, independent observers scored participants with higher biological ages as looking older than their biologically younger peers as well. Participants with an older biological age perceived themselves to be in poorer health than their biologically younger peers. The common saying, “you’re as old (or young) as you feel,” also rang true in this study’s results as well. ![]() Furthermore, scientists found that participants with an accelerated rate of aging performed worse on physical and cognitive ability assessments. ![]() The majority of the participants had biological ages similar to their chronological age, but some participants were found to have aged as much as 3 years physiologically over the course of only one calendar year. With these results, researchers calculated a biological age for each participant and then compared the changes in these measurements over time, yielding a quantified pace of aging. The ‘health’ of each participant’s pulmonary, periodontal, cardiovascular, renal, hepatic, and immune systems were assessed using these biomarkers. These tests measured 18 different biological markers that each form a piece of the aging puzzle. Instead, the scientists’ objective was to reveal more about the aging process in younger people, and therefore provide a foundation for devising preventative therapies for age-related diseases.Ī cohort of nearly 1,000 participants born in New Zealand in 19 underwent extensive testing at ages 26, 32, and 38. ![]() This study was unique in that it did not focus its aging research on older subjects.
