  1. Note. * p < .01; ** p < .001; physical and psychological health indices did not deviate remarkably from available age relevant norms for these measures: K10 [30]; SWL [18]; BMI [31]; SF-36 [32]; forced expiratory volume (FEV) [33]; and timed up and go (TUG) [34, 35]; while HCS step counts are similar to those of older persons in Switzerland, though greater than those in Colorado [36].
