FROM HUFFPO TO US:
The following reference to pain is from The Princess Bride by William Goldman: "Life is pain and anyone telling you different is selling something."
Now that's true and it goes for everybody from religious people to plastic surgeons, but, on the other hand, watch out for someone who wants to sell you a vision of the world that's all pain too. Usually, they've got something behind their back that they want to sell you after they convince you that the world's going straight to hell in a hand basket. I can always spot a fundamentally bent Christian because he's telling me how evil the world is, and, later, he wants to sell me Jesus's love to make me all better. Like most approaches to the "evils" of the world, the best view is a balanced view.
