Zusammenfassung
Jeanne L. Calment, geboren am 21. Februar 1875, gestorben am 4. August 1997 im Alter von 122 Jahren in einem Alterspflegeheim in Arles, Frankreich, war der bisher älteste Mensch, dessen Lebensalter bestätigt ist. In den westlichen Industriestaaten steigt der Anteil der älteren Bevölkerung stetig an. Dies wird dazu führen, dass bis zum Jahr 2050 etwa ein Viertel der Bevölkerung über 65 Jahre alt sein wird. Noch zu Beginn des letzten Jahrhunderts lag die durchschnittliche Lebenserwartung des Menschen in den entwickelten Ländern bei etwa 37 Jahren. Heute beträgt diese etwa 73 Jahre, Tendenz steigend. Den steilsten Anstieg in der Lebenserwartung erlebt seit 1950 Japan, wo das durchschnittliche Lebensalter sogar 87 Jahre bei Frauen und 78 Jahre bei Männern beträgt (Wemmer 1993). Die Gründe für diese immense Verlängerung der Lebenserwartung seit dem letzten Jahrhundert sind vielfältig und werden unter anderem in der verbesserten Hygiene, der veränderten Ernährung und nicht zuletzt in den wesentlich weiterentwickelten Behandlungsmethoden der Medizin gesehen.
