10. The study has references about walking pace being a good proxy for fitness

Walking pace is a central indicator of whole-body physical fitness, frailty, reserve and resilience [6], with self-reported walking pace consistently found to be strongly associated with cardiorespiratory fitness, cardiovascular mortality and all-cause mortality, along with being a powerful marker of longevity [6,7,8,9,10]. Indeed, self-reported walking pace has been shown to be a stronger predictor of cardiovascular mortality than other measures of physical activity or function [9, 10], with self-reported slow walkers having a low life expectancy even in those with normal weight [8]. These findings suggest that self-reported walking pace acts as a simple easy to collect measure of overall physical health status. However, although well researched with cardiovascular and all-cause mortality outcomes, this hypothesis has not been established for infectious disease.
