The statement describes the free-radical theory, which proposes that the accumulated damage from free radicals produced during metabolic processes leads to aging. The cellular-clock theory suggests that aging is determined by the programmed decline of cellular replication and repair abilities. The hormonal stress theory proposes that aging is caused by the body's decreasing ability to cope with stress, and the disposable soma theory suggests that the body allocates resources to reproduction rather than maintaining itself, leading to aging.
