Ageing is an individual process and a universal phenomenon that occurs at different rates in different people. Although the biological causes of development are similar in all cultures, the social experience varies among countries, and even within countries. Adulthood is the period in which a human being reaches the peak of his/her powers. Generally there have three dimensions of ageing: physiological, psychological, and social. Cultural norms and values of a particular society and the combinations of biological maturation, social laws, age role and public policy can determine qualification of ageing. Because of better sanitation, improved public health and the control of life threatening diseases the quality of human life is developing and the quantity of aged people also increasing at an alarming rate. Nowadays aging is deserving attention as a social problem because of increased visibility of the disadvantaged status of the aged. They are now treated as the creator and sufferer section of numerous problems. Developing countries like Bangladesh are especially in a more vulnerable situation in this regard. They are suffering a rapid development in medical, economic, technological, social and cultural development and the number of aged people also creasing more than that. So, it needs especial attention to address this challenge. But, though there have some observable programs to meet this challenge in the developed and welfare states, the initiatives in developing countries, especially in Bangladesh are in a very poor level. Social Work is a developmental and problem solving discipline, but it is neither in a better shape nor a profession in Bangladesh. But, it is the high time to take initiatives toward this upcoming challenge. For that, immediately, there needs collaborative initiative from government, non-government organizations and social work discipline.
