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:

Numerous medical journals have released studies saying women can pass diseases, like syphilis, through breast milk.

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.
