Someone said :
Just look at the animal kingdom.
After the young animal is weaned, do you ever see an adult animal drink milk?
Milk is good for young, growing human children.
Once we reach adulthood it's only because of Kerrygold and other marketing departments that have created an outlet for their products, fooling us into believing we need this stuff in our diets. Look at how many adults are 'lactose intolerant'. Why?
D'oh! The adult body doesn't need it.
Sometimes what is really cute is you see a really big weaned heifer/bullock drinking some milk from a cow
I remember reading somewhere that america has loads and loads of stored butter on account of the preference for skimmed milk. I think most people are lactose intolerant cos it's cows milk... breast milk all the way...
