ABSTRACT
This chapter discusses three principal issues that must be considered in any analysis of the temporal aspects of mobility: the amount of time committed to achieving or preventing mobility; the rate of movement, whether up or down; and the temporal articulation of actions pertaining to mobility. It provides examples for these issues. Commitment of time can range from total to negligible and vary tremendously for different phases of climbing and falling. Most mobile persons must juggle the time at their disposal, allocating various amounts of it to different kinds of activities. Juggling is inextricably linked with motivation. Unless the phrasing and timing of those actions are properly managed, a person's mobility goals (whatever they are) are likely to go awry, even drastically. Because mobility actions occur over time, and anyhow are usually intermittent and meshed with many other kinds of acts, temporal articulation necessarily involves the careful management of transitional phases during the course of mobility.
