Is it normal for a man to be tall 180m and weigh 66kg?

In general, the standard weight is calculated, and the weight is equal to the height minus 105. If the male friend is between 1.7 and 1.8, the calculated weight should be kept at about 70 kg. If you are in this figure, it does not represent the most correct weight figure, but within this weight range, if it does not exceed 10%, it is also the standard weight. Because male friends who are too thin or too fat are not good for their health, if they are too fat, they may lead to chronic diseases, such as hypertension, hyperlipidemia and hyperglycemia. And if they are too thin, they may lead to malnutrition, which will affect the operation of various organs of the body to some extent. Therefore, the male's height is between 1.7 and 1.8, and if the weight is kept at 70 kg, it is a healthy value. Do you think you have reached the standard?
