Look at the nature, who drinks milk? BABIES.

It is not good to drink milk or eat yogurt when you are grown up because it can cause you allergies to lactose, which reduced to almost 0 in cheese process. Also, good to know, cheese contains 10 times more calcium than milk or yogurt!

It is also know that if you have acne, then stopping the consumption of milk MAY improve your skin, specially if you allergic to lactose. You can still drink soya milk if you want!
