Breastfeeding as a lifestyle

My good friend, Sarah, who blogs at Mommy, Ph.D., and I have had several conversations regarding the benefits of breastfeeding. Sarah has frequently argued that many of the benefits associated with breastfeeding are more than likely due at least in part to the lifestyle choices typically made by breastfeeding mothers. I happen to agree. On average breastfeeding mothers are more health and exercise conscious, more concerned about the environment, and more likely to lead healthy lifestyles. Until now, a lot of this was simply speculation on our parts. I just read an article titled "Breast-feeding won't make your baby smarter" that seems to validate our argument.
