Final answer:
The programmed theory of aging suggests that stress hormones in the endocrine system play a role in the aging process. Elevated levels of stress hormones weaken the immune system and can lead to health problems. Stress has also been found to shorten telomeres, which are associated with cellular aging.
Step-by-step explanation:
The programmed theory of aging focuses on the role of stress hormones in the endocrine system.
According to this theory, the accumulation of stress hormones, such as cortisol, can contribute to the aging process.
Sustained elevated levels of cortisol weaken the immune system, which can lead to various health problems.
Additionally, stress has been found to shorten telomeres, which are segments of DNA that protect the ends of chromosomes and are associated with cellular aging.
