<u>Explanation: </u>
There are two types of aging: Primary and Secondary
Secondary Aging comes about when an individual has a lifestyle deprived of healthy life choices and quality medical care.
Poor health choices are the choices that an individual makes which deteriorates the health standard of the individual. These may include substance abuse such as unsubscribed drugs, excessive alcohol consumption and smoking. These poor choices lead to development of certain diseases.
Medical care which does not meet the requirements of the body while it is diseased also puts an adverse effect on the body.
Secondary aging slows down body functioning. For example, the heart becomes weak, blood vessels become clogged and do not function properly leading to other problems, respiratory problems also arise and so on.The process of secondary aging cannot be stopped completely but can only be slowed down. This requires people to change their lifestyle on a major scale.
