Fun Fact: Past the infancy stage, mammals, including humans, are technically not supposed to drink milk. Our bodies don't actually need any of the nutrients it provides, in spite of what people say about it building bones and providing Vitamin D and whatnot. In fact, if you go without drinking it for an extended length of time, your body will realize that it doesn't need it, so when you go to try drinking it again, you'll find you've become lactose intolerant. Happened to my dad.
Not that I really care. I frigging love milk. XD
