Ageing is a natural process. In the words of Seneca “old age is an incurable disease”, but more recently Sir James Sterling Ross commented, “you do not heal old age you protect it: you promote it; you extend it” [1]. The geriatric population is defined as population age 60 years and above [2]. In order to make world familiar with the old age problems world health organization celebrated WORLD HEALTH DAY (WHO) with “Active aging makes the difference” as slogan and declared the year 1999 as international year for older persons [3].
