We can often see the figure of the time machine in movies and television, through which we can not only know our future in advance, but also change what we regret or want to do but do but not do. However, there is no time machine in the world, we can't know how long our life expectancy is, although aging is an irresistible thing, but our fate is always in our own hands.

Knowing the signs of aging in advance can prevent it in advance and delay the rate of aging. For men, how can they judge for themselves whether they are old?

Men are not old, look at these 3 places to know that a person who does not occupy is still very young.

1. Physical strength

Young men are always energetic when it comes to physical work and don't get out of breath quickly. Older men, on the other hand, will feel powerless when they do something that requires physical exertion. Therefore, if you feel that your physical strength has decreased significantly, not as much as before, it means that you are starting to get older.

2. Hair

We all know that when the life of a tree comes to an end, the branches and leaves on the trunk become more and more scarce, and for people, hair is like these leaves. As we age, our skills deteriorate, and not only does the melanin in the roots of the hair decrease, but the hair becomes grayer and whiter, and hair loss occurs.

Therefore, men can also tell if they are old by looking at their hair.

3. Brain

Teenagers always have better memory, not only because they often use their brains to think, but also because the cells in the brain are more vigorous. And for men who are already young, their memory will become less than before, and their forgetfulness will become bigger and bigger.

In this case, male friends can exercise their memory by writing more diaries, recalling, etc., if left unchecked, it may form senile dementia in the later stage.

In general, if a man wants to know whether he is old or not, he can know through the above 3 places. If you are more afraid of aging, you will invisibly add pressure to yourself, and you will age faster
