Ageing or aging (see spelling differences) is the process of becoming older. The term refers especially to human beings, many animals, and fungi, whereas for example bacteria, perennial plants and some simple animals are potentially immortal. In the broader sense, ageing can refer to single cells within an organism which have ceased dividing (cellular senescence) or to the population of a species (population ageing).In humans, ageing represents the accumulation of changes in a human being over time,[1] encompassing physical,psychological, and social changes. Reaction time, for example, may slow with age, while knowledge of world events and wisdom may expand. Ageing is among the greatest knownrisk factors for most human diseases:[2] of the roughly 150,000 people who die each day across the globe, about two thirds die from age-related causes.The causes of ageing are uncertain; current theories are assigned to the damage concept, whereby the accumulation of damage (such asDNA oxidation) may cause biological systems to fail, or to the programmed ageing concept, whereby internal processes (such as DNA methylation) may cause ageing. Programmed ageing should not be confused with programmed cell death (apoptosis).The discovery, in 1934, that calorie restrictioncan extend lifespan by 50% in rats has motivated research into delaying and preventing ageing.
