..It is actually common to feel younger than we are. A 2018 study with 33,751 respondents showed that once people pass the pivotal age of 25, they typically rate their subjective age as younger than their chronological age. And this discrepancy grows as we get older – for every decade that passes, people tend to feel that have only gained five or six years. This is the equivalent to living Martian years as opposed to Earth years.
It turns out that this phenomenon may have rather important implications. A recent surge in research in this area has revealed that the extent to which people feel younger than they are is strongly associated with a whole range of health outcomes. People with a younger subjective age are less likely to suffer from diabetes, hypertension, depression, cognitive impairment and dementia. These people also tend to report better sleep, better memory function and more fulfilling sex lives.
People with a younger subjective age also view their future selves in a more positive light and are more likely to walk faster. One group of researchers even found that people with a lower subjective age have a younger looking brain. Brain scans showed that they had more grey matter overall, with particular resilience in areas called the prefrontal cortex (involved in planning and complex cognitive behaviour) and superior temporal gyrus (responsible for processing sounds and emotions).
Something I’ve experienced, recognized for most of my adult life. Turns out this doesn’t surprise scientists studying folks’ aging…after all.
