What does this mean? Well, you’re a musician, so you save your receipts for tax purposes. You handle them, put them in your purse or wallet, sort them and count them. It’s now proven that a dangerous chemical, bisphenol-A, is found on them. You need to be aware.

(From the article:)

First synthesized in 1891 and developed in the 1930s as a synthetic form of estrogen, bisphenol-A has been widely used in commercial products including plastic bottles, compact discs and dental sealants. While it was regarded as safe for decades, recent research using sophisticated analytic techniques suggests that low doses of the compound can interfere with the endocrine system and cause a range of health effects, including reproductive problems and cancer.
