Why These Areas Matter
The World Health Organization defines healthy ageing as “the process of developing and maintaining the functional ability that enables wellbeing in older age.” Functional ability includes mobility, thinking, learning, maintaining relationships and participating in society.
Research from the National Institute on Aging and WHO highlights that healthy aging can be supported by staying physically active, making healthy food choices, getting enough sleep, managing stress, staying socially connected, and keeping the mind engaged.
TurnBackClock’s assessment is inspired by established healthy-aging research and public-health guidance. The scoring system itself is an educational model created for this website. It is research-informed, not medically validated.
