After much thought, I have tentatively concluded that a society that thinks it necessary to print on plastic bags warnings against sticking your own or your children’s heads in them is a society so far gone down the path of infantilism and idiocy that it should probably stick its own collective head in a plastic bag and put an end to itself.
Similarly, monitions that things cooked in ovens are hot, that bread contains wheat, or, on a bag of peanuts, that “this product is packaged on shared equipment with peanuts…”, suggest that government agencies are staffed by persons who believe the populace to be imbeciles and that, since the public puts up with these 'warnings', the agencies may be right.
Bah, humbug!
