Studies indicate that biological age does not always align with chronological age, with four primary factors influencing the rate of aging. Chronic stress leads to elevated cortisol levels, which can impair immune function and accelerate cellular aging. Chronic inflammation, often stemming from poor diet and lack of exercise, is another significant contributor to aging, as it is linked to numerous diseases. Additionally, the length of telomeres, which shorten over time, serves as a crucial measure of cellular aging, and lifestyle choices can influence this process through epigenetics. Finally, the connection between passion and longevity suggests that a fulfilling life can rejuvenate the body and mind, countering the effects of aging. The article emphasizes that individuals have substantial control over their aging process through lifestyle modifications, including stress management, diet, and maintaining a sense of purpose.
