This chapter discusses the basic biology of ageing. First, it examines the social construction of age which emphasises that what biologists or biogerontologists understand as ageing, cell senescence, is only one manifestation of a complex phenomenon. Second, it provides an overview of the biology of ageing from theories of ageing processes to the idea of normal ageing. Third, it considers what might be done to modulate cellular ageing, such as calorie restriction, inhibiting stress and supplementing the immune system. It concludes by discussing the ethics of interventions in the ageing process.

Keywords:   ageing biology, biogerontologists, cell senescence, calorie restriction, stress management
