many mammals love dairy, i grew up on it; I have no teeth, same as my dad and brothers as proof I grew up on dairy------I also grew up with a sore throat every winter that lasted all winter and many times turned into not being able to breathe very well----what they call croup about did me in every winter as a child.
we mammals can eat and drink poisons all our life-----many a old timer drank arsenic and some mercury and many lead. I had 112x more lead than a normal male my age in 50 countries-----but that lead never did me any good.
