    So much for the idea of aging gracefully – or gradually. New research suggests the body ages in bursts, in particular, rapid changes about age 44 and another when we hit 60. We consider aging as ...

    Normal aging is associated with telomere shortening in both humans and mice, and studies on genetically modified animal models suggest causal links between telomere erosion and aging. [10] Leonard Hayflick demonstrated that a normal human fetal cell population will divide between 40 and 60 times in cell culture before entering a senescence phase.

    After age 30, the mass of the human body is decreased until 70 years and then shows damping oscillations. [24] People over 35 years of age are at increasing risk for losing strength in the ciliary muscle of the eyes, which leads to difficulty focusing on close objects, or presbyopia. [27] [28] Most people experience presbyopia by age 45–50. [29]

    Lenart and Vašku (2016) [45] have also invoked evolvability as the main mechanism driving evolution of ageing. However, they proposed that even though the actual rate of aging can be an adaptation the aging itself is inevitable. In other words, evolution can change the speed of aging but some ageing no matter how slow will always occur.
