: In fact, there is no relation between age and weight. Why not body composition is the same with age. In some cases it was found that he was 24+ but weighed 50 while in others it was seen that he was 15 but weighed 55/60 +. There are boys and girls who are very young but their body and weight are much higher. They are taller and some are shorter. Basically if you determine your exact weight then your hide , age , body size. It is necessary to know these three correctly then it will be possible to determine the correct weight. Why is it not seen that the age of a person is 18, his height is 5 feet 5 inches, but because he is healthy, that is, due to his excess fat, his weight is 60/62 +, but it is not normal in that case which is a health risk. So I would say that if you weigh yourself, you can measure it yourself. First, you should know the size of your body (chest / abdomen) weight , and the correct age, then comment or take the advice of a doctor. I hope you understand me.
