Speaking about the amount of water in the body, we should acknowledge its decline with aging. According to Russian studies,2 the amount of water in the fetus is 95%, in the baby – 92%, and it constantly decreases. Between age 20 and 30 the amount of water in the body is 70%, between age 40 and 50 it is 50% (this is when the wrinkles appear). After the age of 70, the amount of water in the body drops down to 30%. This is when the bones become brittle because there is no enough water in them to keep them elastic.2
