It is so strange that they like to get money from others and carry out the experiment. Why not take a simpler way. Ask those cancer patients about their frequency of milk drinking, We know the answer at once. Those who do not get money from the dairy company may get money from their enemy, eg, fruit company, soy milk company, how can we know they do not have some advantages from those non-dairy companies. Therefore, we never know the truth in this foolish way.
