If these symptoms occur, it means you are aging.

Phenomenon 1: Weak athletic ability

Tip: If the phenomenon of rapid heartbeat continues for a long time after exercise, the heart's regulatory ability will become lower and lower, which means that the heart's own reserve capacity has decreased. This is caused by the aging and weakening of heart muscle elasticity, which is related to poor vascular health.

Phenomenon 2: Panting

Tip: If you feel out of breath after climbing stairs or running, it means your lung function is starting to decline. Studies have shown that if you don’t exercise scientifically, your lung function will start to weaken after the age of 20.

Phenomenon 3: Dirty Teeth

Tip: Men's teeth tend to become dirty after the age of 30, which is related to not paying attention to oral hygiene. If the brushing posture is incorrect and the teeth are not brushed thoroughly, the gums will gradually shrink, the gaps between teeth will become wider, the tartar will increase and deposit in the gaps and around the gums, the dental plaque will become active, and the oral hygiene will be poor. Therefore, you should change your teeth brushing in the morning and evening to brushing your teeth in the correct posture after every meal.

Phenomenon 4: Fatigue

Tip: If a 30-year-old male is always lacking energy and listless at work or in life, it may be caused by psychological pressure or endocrine changes. This indicates that the androgen level has dropped.

Men should pay more attention to their physical changes after the age of 30, have regular checkups, seek medical attention promptly if anything is wrong, develop healthy living habits, and slow down aging.
