Zodiac,
You said that you refer to facts, and that I just state what I wish were true. You also said to show you proof that a study can be found to support any assumption. I will be fair, and offer proof of what I believe the studies show, as well as some studies that proport to support what you have to say. From what I have gathered, the studies you seem to have based your assumptions on have been refuted by later studies. I will provide links here, for those who wish to study this further.I assure you that as soon as you read one statement and are sure it has the facts, you will find another that contraindicts it.
