eek, BPA found in receipts

NBC recently ran a feature claiming "human exposure to the controversial chemical bisphenol A, or BPA, is much higher than some previous estimates and likely comes from some sources that are still unknown." One newly discovered source they highlight is cash register receipts, with studies showing that BPA is rubbed off on consumer's hands when receipts are handled. And apparently companies worldwide use register receipt paper that's laden with the substance. BPA is shown to mimic hormones, and exposure over time is linked with breast cancer in women because our bodies have a difficult time completely ridding our systems of the substance once exposed. And as we continue to find new ways that BPA gets in our systems, I wish I had a better conclusion than awareness here, but, I guess that's where change starts.
