What is the meaning of ageing?

Ageing relates to the process of becoming old. In humans, ageing represents a number of changes in a person over time and includes physical, psychological, and social changes also. 

The cause of ageing is uncertain; current theories say that ageing occurs due to the accumulation of damage, which may cause the biological system to fail.

The programmed ageing concept says that ageing occurs due to certain internal processes such as DNA methylation, etc which may cause ageing.
