Given the source of the quoted material, The Huffington Post, I'm not inclined to think of it as authoritative. Like all such sources, some of what they say is bang on, too much of their material is unsupported opinion. I treat information from them, 60 minutes (especially 60 Minutes' dismal record in health reporting), and Fox for that matter, as unreliable. I would probably look for a more authoritative source. Your job is to find one on this topic - I'm too lazy.
