What does the word aging mean?
becoming old or older; showing signs of growing old: Many of us are caring for an aging parent in declining health.
In broader terms, aging can be broken down into three distinct and often related categories: biological aging, psychological aging, and social aging.
Common conditions in older age include hearing loss, cataracts and refractive errors, back and neck pain and osteoarthritis, chronic obstructive pulmonary disease, diabetes, depression and dementia. As people age, they are more likely to experience several conditions at the same time.
Such causes of aging include but are not limited to oxidative stress, glycation, telomere shortening, side reactions, mutations, aggregation of proteins, etc. In other words, it is the progressive damage to these structures and functions that we perceive and characterize as aging.

Exposure to light is a top cause of premature aging: Sun exposure causes many skin problems. Ultraviolet (UV) light and exposure to sunlight age your skin more quickly than it would age naturally. The result is called photoaging, and it's responsible for 90% of visible changes to your skin.
Natural changes happen in the body as we age, such as skin damage from sun exposure, loss of muscle and physical strength, loss of some sight and hearing, as well as changes to our sleep patterns, energy levels and appetite.
An individual who experiences chronic stress is more likely to make unhealthy lifestyle choices, which causes additional health problems. In other words, stress accelerates aging, and aging causes stress—it's a vicious cycle. Stress also affects the body on a cellular level.

What is the difference between ageing and aging?
In Canada and the U.S. , the preferred spelling is aging. British usage favours the variant ageing, which is also accepted in Canada.
The decline in the force of selection with age is viewed as the fundamental cause of aging (4). It is why, starting at reproductive maturity, senescence—increases in susceptibility to death and decreases in fertility—should be inevitable in all multicellular species capable of repeated breeding (4).
