For the most part this year, we have talked about actual food. Granted, this is to be expected. (It is food studies after all.)

I do not care enough to track down the pesticides and herbicides used on every piece of fruit I eat.) Well, BPA has been in the news recently and I’ve been wondering what the hell it is. So, with out further ado, the BPA wikipedia page.
