Milk

One of my sons,a freshman at a junior high school,belongs to a volleyball team in his school.He practices volleyball for six days in a week and he enjoys it a lot.I am very happy to see his joy.I don't know much about volleyball but one thing is obvious; tall players are more advantageous for the sport.Unfortunately, he is not very tall now.Recently,someone told him that the more people drink milk,the taller they will be and he drinks milk as much as he can;at breakfast,lunch and before sleep at night.I think he will be taller soon and I hope he won't get any stomach troubles due to drinking too much milk.
