Aging 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 & memories may slow with age, while general knowledge typically increase. Ageing is associated with increased risk of cancer, Alzheimer's disease, diabetes, cardiovascular disease, increased mental health risks, and many more. Of the roughly 150,000 people who die each day across the globe, about two-thirds die from age-related causes. Certain lifestyle choices and socioeconomic conditions been linked to ageing. Current ageing theories are assigned to the damage concept, whereby the accumulation of damage (such as DNA oxidation) may cause biological systems to fail, or to the programmed ageing concept, whereby the internal processes (epigenetic maintenance such as DNA methylation) inherently may cause ageing. Programmed ageing should not be confused with programmed cell death (apoptosis). in heaven Christians and jews are young again even though they died old ;it is written in the Holy Bible the word of the Lord according to prophet it is written in the Holy King James Bible the word of the Lord according to saint isaiah the prophet 700 BC Before Christ Isaiah 40:31 But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run & not be weary; & they shall walk & not faint. amen Hallelujah Hallelujah Blessed be the word of the Lord for Christ is risen Hallelujah Hallelujah  peace be still in Nomine Patris et FiLii et Spiritus Sancti amen
