| '''Ageing''' (British English) or '''aging''' (American English) is the accumulation of [[changes]] in an [[organism]] or object over time. Ageing in [[humans]] refers to a multidimensional [[process]] of [[physical]], [[psychological]], and [[social]] [[change]]. Some [[dimensions]] of ageing grow and expand over time, while others decline. [[Reaction]] time, for example, may slow with age, while [[knowledge]] of world [[events]] and [[wisdom]] may expand. [[Research]] shows that even late in life, [[potential]] exists for [[physical]], [[mental]], and [[social]] growth and [[development]]. Ageing is an important part of all [[human]] [[societies]] reflecting the [[biological]] changes that occur, but also reflecting [[cultural]] and societal [[conventions]]. | | '''Ageing''' (British English) or '''aging''' (American English) is the accumulation of [[changes]] in an [[organism]] or object over time.
