We read with interest the article by Cavanaugh and colleagues (1) concerning the natural ambulatory activity patterns of older community-dwelling adults. The use of nonlinear analysis to describe habitual activity is an area of emerging research, prompted by the limited value in reporting the amount of physical activity, such as the number of steps walked in a day. Timing, duration, and variability of activity may be relevant to health and successful ageing.
