Interestingly, however, the people with younger subjective ages also became more conscientious and less neurotic – positive changes that come with normal ageing. So they still seem to gain the wisdom that comes with greater life experience. But it doesn’t come at the cost of the energy and exuberance of youth. It’s not as if having a lower subjective age leaves us frozen in a state of permanent immaturity.
Feeling younger than your years also seems to come with a lower risk of depression and greater mental wellbeing as we age. It also means better physical health.
