For men, it is better to be aware of their signs of aging than carelessness; to realize that talking to one's feelings afterwards is better than pretending to be a good one; it is not enough to merely stop at the verbal discussion. Is it clear about aging? All kinds of signs are more important for prevention. Phenomenon 1: Vision loss The problem of the eye itself was ruled out, which shows that there was a disorder in the blood vessels. It affects the blood circulation, causes metabolic disorders of the optic nerve, and causes vision loss. Phenomenon 2: hair thinning At the peak of the career, mental and psychological pressures increased, causing endocrine and blood circulation disorders, which caused hair loss and sparse hair. Phenomenon III: Hearing loss If the inner ear has poor blood circulation, hearing loss will occur. In addition, the noise of the city is large, and young people love to wear Walkman. When people are young, they may not feel the degree of hearing damage. However, after 30 years of age, the harm of hearing loss can be clearly felt. Phenomenon 4: Decreased sexual impulses The reason that the 30-year-old man's sexual ability declines comes from both psychological and physical aspects. The mental fatigue, mental stress, physical androgen levels, and poor blood circulation all contribute to erectile dysfunction. Phenomenon 5: Weak exercise capacity The phenomenon of rapid heart beat after exercise and long-term adjustment of the heart is decreasing, indicating that the heart's own reserve capacity has declined. This is caused by the aging of the heart muscle and the weakened elasticity, which is related to poor blood vessel health. Phenomenon 6: Breathless After going up the stairs and gasping after running, the lung function began to decline. Studies have shown that without scientific training, people’s lung function begins to fade after 20 years of age. Phenomenon 7: Dirty teeth After 30 years old, the teeth are easily dirty, which is related to the lack of attention to oral hygiene. If the brushing posture is not correct and the brushing is incomplete, the person's gums will gradually shrink, the teeth will become wider, the calculus will increase and be deposited around the teeth and gums, the plaque will become active, and the oral hygiene will be poor. Therefore, you should change your morning and evening brushing to correct posture after every meal. Phenomenon 8: Insufficiency If a 30-year-old man is always inactive at work or in life, he is listless and may be caused by stress or endocrine changes. This shows that the level of androgen has dropped.
