AI overview
Ageing is the biological process of becoming older, which occurs in humans, many animals, and fungi, though some organisms like bacteria and certain plants can potentially live indefinitely. Understanding ageing matters because it affects how bodies and populations change over time, though the underlying reasons why most living things age remain an important area of study.

Ageing (or aging in American English) is the process of becoming older. The term refers mainly to humans, many other animals, and fungi; whereas for example, bacteria, perennial plants and some simple animals are potentially biologically immortal. In a broader sense, ageing can refer to single cells within an organism which have ceased dividing, or to the population of a species.
In humans, ageing represents the accumulation of changes in a human being over time and can encompass physical, psychological, and social changes. Reaction time, for example, may slow with age, while memories and general knowledge typically increase. Of the roughly 150,000 people who die each day across the globe, about two-thirds die from age-related causes.
