Jack LaLane - the world's first renowned fitness guru - eloquently stated that no animals drink milk once they're off their mother's teet so why the hell should we keep drinking it. I agree. Especially if you are a grown man.
Oh Jack LaLane.
Animals stop drinking milk because warm farm titty milk sucks. They don't know what a cold glass of milk and a log of raw cookie dough can do. If those poor dumb animals had the means and access to a Krogers....they would go absolutely hog wild in there, and likely find more ways to use milk than we even know about.
