The normal aging process is BEST defined as:
b) Physical and mental capacities decline gradually over time
During the normal aging process, physical and mental capacities tend to decline gradually as individuals grow older. This decline is a natural part of aging and can vary from person to person. It includes changes in various aspects such as vision, hearing, memory, muscle strength, and overall cognitive functions. While aging is a normal and inevitable part of life, maintaining a healthy lifestyle, staying active both physically and mentally, and seeking proper medical care can help individuals age gracefully and maintain a good quality of life as they grow older.
