Didn't Carnation, way back in the '50s,  used to have an ad campaign about
their evaporated milk coming from contented cows?

Which brings up a somewhat related question.  There is so much in folklore
about babies being affected by their mothers emotional state.  Milk from
tense mums causes wind (as they say in the real English-speaking countries)
and all that.....could there be any basis for this?  It's such a  pervasive
belief, ya gotta wonder.
