Biomedical Science & Research Journals | Aging: Basic Concept

Today, people are living longer than ever before due to advances in education, technology, medicine, food distribution, and sanitary conditions. So, nowadays, it is not unusual to meet people who are in their 70s, 80s, 90s, and some who are close to 100 years old. However, “adding the years to life,” does not mean that we are also able to “add more life to the extra years.” In other words, living longer does not always mean we will also have better or a good quality of life in later years. Some older adults in late life are healthy and independent and are still very involved in their family and community lives. Then again, it is not unusual to see older persons who can get very ill and are not able to get themselves out of bed.

Aging is a lifelong process of growing up and growing old. It begins at conception and ends with death. So, in this sense, we are all aging from the time of birth. In our younger years, aging is called by other names. For example, in our infant years, we call aging “growth and development.” In our teenage and young adult years, we refer to aging as “maturation.” After age 30, our physical body begins to wear out and our functioning declines. This is called “senescence.”

Aging includes three parts:
A. Growth and development: In our infant years
B. Maturation: In our teenage and young adult years and
C. Senescence: After age 30. So, aging should be explained based on these three parts.


The human body changes in many noticeable ways with age, and aging is often accompanied by decline in bodily functions. However, a decline in function is different from loss of function that results from disease. Perhaps the first sign of aging occurs when the eye cannot focus easily on close objects. Often by age 40, many people find it difficult to read without using glasses. Hearing also changes with age. People tend to lose some ability to hear the highest pitched tones. Therefore, older people may find that violin music no longer sounds as exciting as it did when they were younger. Our skin wrinkles and our hair turn gray or white.
