no mammal on earth drinks milk past infancy.. and even as infants we drink our mothers milk, not milk from another animal
i do not drink milk and it does more harm than good. in fact the stats are right there in black and white.. the US drinks more milk than any other country and our diabetes, heart problems, bone problems, obesity etc blow away every country. the highest milk drinking states are in middle america and the south, and they ironically have the worst health stats. go figure.
if the US banned milk we wouldn't solve all our health problems, but i would argue we would get much healthier
