Aging is a steady, and continuous process of human life. As we grow older, many bodily functions begin to gradually weaken and can present seniors with various health challenges. According to the World Health Organization (WHO), people 60 years old and above are referred to as older or elderly persons (1). People of this age group are more susceptible to developing diseases and thus, preventive health care (PHC) is highly recommended for them. To put it precisely, prevention is better than cure.

Aging is a part of human life. Human life starts with birth, then it enters the stages of childhood, adolescence, adulthood, and finally old age. Aging is an inevitable and irreversible process. It is estimated that elderly people account for about 12 percent of the world’s population–and this is rapidly increasing to over 22 percent by 2050 (1). As we grow older, a wide range of changes happens in the body to varying degrees, which could result in different health issues. According to the World Health Organization (WHO), people 60 years old and above are referred to as older or elderly persons (2). People of this age group usually have high chances of developing diseases and preventive health care (PHC) is highly recommended for them. To put it accurately, prevention is better than cure.
