Answer to Question 1

Elderly people don't seem to notice thirst as clearly as younger people do. Research showed that the thirst-regulating mechanism of older adults was less effective than that of younger individuals. Younger men reported being thirsty and having dry mouth after fluid deprivation, while older men reported no change. Younger people made up for fluid loss in 24 hours, while older people did not drink enough to achieve their prior state of hydration. It appears that dehydration occurs more quickly after fluid deprivation and that rehydration is less effective because of lower thirst sensation and reduced renal water conservation capacity.
