Once i see an adult bull drink milk from a cow, even the guide of the park was dismayed. :/
...And considering we don't even drink milk from our own species, we humans add a touch of bestiality to our perverse drinking habits. :/
There's more than a few doctors who strongly advocate we NOT drink milk as adults, at least not as a tall glass of it straight.
All animals become lactose intolerant at a certain age to wean them from their mother's teat. This includes humans except some of us have developed a tolerance to milk and you can make yourself Lactose Intolerant if you stop drinking milk for a year.
