While the fear of falling is a common psychological consequence of falling, older adults who have not fallen also frequently report this fear. Fear of falling can lead to activity restriction that is self-imposed rather than due to actual physical impairments. Evidence suggests that exercise can significantly improve balance confidence, ...

In social insects, cuticular hydrocarbons (CHCs) play an important role in nestmate discrimination processes, but young individuals are usually not discriminated. We studied CHC changes in young workers of the social wasp Polistes dominulus. A quantitative estimation demonstrated that total quantities of CHCs increased after emergence, with branched alkanes increasing ...

A healthy diet and regular exercise are among the major factors that influence quality of life (QOL) in old age. Exercise is believed to be beneficial to improve QOL, retarding age-related decline of physiological functions and preventing age-related diseases. Regular physical exercise can possibly improve age-related functional decline and delay ...
