Contraceptive Use in the United States
According to the article, 62% of all women of reproductive age use some form of contraception. I didn't realize that non-sexual related use of contraceptives was so epidemic in the US. Hopefully, there are serious research teams and research dollars looking into finding a permanent cure for this "malady".
