The majority of people are white, that's why blacks are called minorities. Your statement makes you captain oblivious.

First, modern milk cows have been breed to produce far more milk then her calf could ever drink. Beef cows have been breed to reach slaughter weight very quickly. Second, both are still regular cows. Third, pain from full udders did not originate from humans, that's pure nature. Fourth, milkflow does stop eventually if milking is slowed down, but these cows are literally alive for only one reason, to make milk. Fifth, constant pregnancies are needed because long periods between calves will actually decrease milk quality. This is a long post, but it's best to know what you're actually talking about.

Me thinks both of your techniques are off, the forehead should not provide friction.
