If you had to drink a pint of blood a day - human blood, pig blood, it doesn't matter - would you develop a taste for it? Would you miss it if you developed this habit and then it was stopped? What if drinking blood was common and drinking milk vulgar to suggest? What if you were transported to a society where drinking milk was as taboo as drinking a pint of blood might be here. If somehow in that society you could find milk - cow milk, human milk, it doesn't matter - would you drink it? If you drank it, would you tell anybody?
Knowing what I know now, I'm not sure if I would drink the milk. I'm almost certain I would not tell anybody.
I know guys that would: www.aquariusrecords.org. They 'got' Berkowitz Lake & Dahmer.
Regardless of which world you are in, the milk drinkers or the blood drinkers, mix the two - 50% milk and 50% blood. Tell people it is a strawberry soy product. Only volunteer information if asked.
