When's the last time you had a glass of cow's milk?
Americans are drinking a lot less milk than they used to. According to the U. S. Department of Agriculture, the average person drinks 18 gallons a year. Back in the 1970s it was more like 30 gallons a year. We once hoisted a glass with dinner, soaked our breakfast cereal or dipped into the occasional milkshake. This habitual milk drinking was no accident.
