Nine Physiological Changes in Male Aging: A Scientific Perspective from Declining Brain Storage to Reduced Sexual Drive [i]

People often lament, "I'm getting old, I'm not as 'strong' as I used to be" [i]. In fact, as we get older, our bodily functions will naturally decline [i]. When experts analyzed the problems faced by men, they found that although the aging of men's bodily functions does not have a clear physiological change process like menopause in women, some almost irreversible aging changes will occur from the age of 20 to 30 [i]. (1) Brain function: The ability to concentrate and language skills do not change much with age, but the ability to store and retrieve information begins to decline from the age of 30, although not obviously, but steadily [i]. (2) Cardiac responsiveness: After the age of 30, the heart's acceleration response begins to decline, and the maximum heart rate per minute decreases by an average of 10 beats per 10 years [i]. (3) Endurance: Due to the decline in the body's oxygen supply capacity, work capacity gradually decreases, and at the age of 70, work capacity is only half of that at the age of 30 [i]. (4) Body fat: Starting from age 20, the ratio of body fat to muscle tissue tends to increase. The older you get, the more difficult it is to exercise. Muscle strength and plasticity begin to decline from age 20. By age 40, the function of the heart and lungs gradually weakens, joints and ligaments harden, and the body becomes more and more susceptible to injury [i]. (5) Muscles and bones: With age, muscles atrophy and muscle strength weakens, but this change can be compensated for by physical exercise [i]. Although bone loss is a common feature of aging, the rate of decline can be slowed down by exercise [i]. (6) Hair: With age, the number of hair follicles on the scalp decreases, and the remaining hair grows at a slower rate [i]. (7) Hearing: The eardrum thickens, the ear canal atrophies, and it is difficult to hear pure tones (sine wave) and high-frequency sounds, especially when approaching age 60 [i]. (8) Lung function: Due to hardening of the chest wall, the burden on the respiratory muscles increases, more air remains in the lungs after each breath, the number of breaths increases, and chest tightness increases [i]. (9) Frequency of sexual urges: The frequency of sexual urges varies from person to person, but it is inevitable due to the decrease in sex hormone levels and vitality; after reaching its peak at age 30, it decreases by about 30% every 10 years [i]. A large amount of clinical data tells us that prostatitis, benign prostatic hyperplasia, orchitis, epididymitis, hydrocele, spermatorrhea, premature ejaculation, impotence, anejaculation, penile cancer, etc. are all common diseases that harm men's health and torment many men [i]. These changes clearly tell us that as we age, our bodies will naturally weaken and illnesses will follow [i]. Moreover, due to the fast pace of modern urban life, urban men have more social engagements, increased life and work pressure, and irregular diet, daily life, and exercise, physiological fatigue, which used to appear in most men around age 40, is now appearing in many men around age 30. This makes it even more necessary for men to pay attention to their bodies early and take care of themselves in advance to avoid regrets later [i]. So, how can men get on the fast track to health? Experts have put forward some suggestions [i]. First, be a little muddle-headed and carefree [i]. That is, be clear about important matters, but muddle-headed about trivial matters [i]. Stand tall, see far, be broad-minded, and have a big heart; this makes life and work easier [i]. Second, find joy in helping others, be content with what you have, and find joy in yourself [i]. At the same time, maintain a reasonable diet, exercise appropriately, quit smoking and limit alcohol consumption, and maintain psychological balance [i]. Be aware of the four major obstacles affecting male longevity: not easily shedding tears, not liking to talk, not seeking medical attention when sick, and not liking to go home [i]. Modern people have four different attitudes towards health: the first type is the smart person, the second type is the insightful person, the third type is the ordinary person, and the fourth type is the muddle-headed person [i]. Four attitudes, four outcomes [i]. Smart people actively pay attention to health and invest in health, resulting in increased health value; insightful people pay attention to health and save on health, resulting in preserved health value; ordinary people ignore health and are indifferent, resulting in decreased health value; muddle-headed people overdraw their health, get sick prematurely, die prematurely, and have a lower quality of life [i]. Clearly, everyone is equal before health; you reap what you sow; you get what you work for. Shouldn't you take the initiative to be a smart person? [i]
