As a kid I drank milk that went from the cow to the gallon size glass jar after being poured through a piece of cotton bed sheet or handkerchief to the refrigerator. Sometimes I even drank it warm before it went into the fridge. At about age 10 or so dad decided it was too much trouble to keep a milk cow so we started buying milk from the store. Haven't had any processed milk since then. I'm still alive and fairly healthy.
