I read some very interesting information recently. According to some experts (including a PhD who has worked at the FDA), a link has been found between the chlorine in our water and breast cancer. Even more alarming, the chlorine in shower water is transformed to a potentially dangerous form when water becomes steam, so experts advise not to take long showers. Getting a shower filter (and filter for your drinking water) is very inexpensive, and if this information is true, doing so may just save your life.
