If you have started feeling your age or even older, stop right there! Feeling younger makes us feel better and healthier both physically and mentally; at least so say researchers from Germany. They examined longitudinal data collected over a period of three years (2014–2017) by the German Ageing Survey, with a mean age of 64 years (40–95). Controlling for baseline functional health and sociodemographic variables, they found that greater perceived stress was associated with a steeper decline in functional health, which increased with advancing chronological age. However, they also found that those who felt younger than their age showed a less steep decline in functional health and greater perceived stress was less strongly associated with functional health decline. Furthermore, they were less likely to feel stressed and this stress buffer effect was greater with increasing age.
