The physical environment, as it relates to the dependencies of older adults, remains one of the most overlooked areas in environ­ mental design. In order to move beyond this status quo, persons responsible for planning that environment must develop a new un­ derstanding of ways in which their influence can improve the older adult’s physical and mental functioning. This section deals with age-related changes in vision, hearing, taste, smell, touch and kin­ esthetic systems, and provides recommendations for environmental adaptation and modifications which may compensate for the changes in each of these systems.
