This article concentrates on the concepts of time that are implied in the study of ageing. As such, it does not directly address the complex issue of autonomy and ageing, but is an attempt to prepare the ground for a more fundamental approach to ageing than is usually the case. Instead of assuming that we know what age is, I intend to think a little more about the concepts of time that are presupposed in speaking about age and ageing. Usually these concepts are approached from a chronological time perspective, which is only one, albeit important, approach to time. Another perspective which is crucial for understanding human ageing is subjective, personally experienced time. These perspectives are not by definition in harmony with each other. Subjective perspectives on time and ageing can conflict with objectifying, chronological perspectives. Human ageing means living in dimensions of time where impersonal forces and regularities clash with personal meanings.
