Normal ageing is the result of a complex process that is progressive in nature, in the absence of disease. It is important to note that the speed of ageing varies by individual. In the same way, major morphological and functional differences can be observed between individuals of the same age.
Simply so, what is an example of normal aging?
For example, as people age, the lens of the eye thickens, stiffens, and becomes less able to focus on close objects, such as reading materials (a disorder called presbyopia). This change occurs in virtually all older people. Thus, presbyopia is considered normal aging.
One may also ask, what are normal aging diseases?
Normal aging includes vascular remodeling and vascular stiffness (21). Atherosclerosis causes inflammation and further vascular changes (22) increasing risk for cardiac events, cerebrovascular events, peripheral vascular disease, cognitive impairment, and other organ damage.
