Recent developments in epigenetics suggest that our epigenome—the chemical changes that happen above our DNA sequence—might be the key to understanding and calculating human biological aging. The programmed theories imply that aging follows a biological timetable, perhaps a continuation of the one that regulates childhood growth and development. Ageing or aging (see spelling differences) 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.
