I especially like this quotation from Phil Plait at the blog, Bad Astronomy:
"once you buy into one flavor of candy-coated nonsense, they all start to taste pretty good. But we have to be adults here, and understand that you can’t live on candy. In fact, too much makes you sick."
Right now my brain is a little fried from working on my poster all day, but this was enough to pull me into focus, if only for long enough to share it with you. :)
