Aging occurs in bursts, not steadily, study finds

Recent research suggests that aging may not be a steady process but occurs in bursts. Scientists have found that certain age-related changes in the body happen more rapidly at specific ages, particularly around 44 and 60. Studies have tracked molecular signals in blood samples, revealing significant changes in metabolism and immune function during these periods. Other research on mice indicates distinct stages of aging, while some experts propose that aging may occur in longer phases rather than short spurts. Ongoing studies aim to clarify how these molecular changes relate to aging and health. Researchers are interested in understanding individual differences and the impact of lifestyle factors on the aging process.
