Apparently a growing number of people are purchasing frozen breast milk online. I have no idea how many, but there is a buy and sell page. If you're an adult and you think drinking breast milk is a good idea, here's why you're wrong:

Also, cow milk is heavily regulated because it is so easy to contaminate milk with a variety of dangerous viruses and bacteria.

If a woman consumes alcohol, tobacco, caffeine and drugs -- legal or otherwise -- they end up in the milk.

Cow's milk is actually more nutritious... if you're an adult. So don't be stupid.
