"I’m having trouble deciding whether I understand the world better now that I’m in my seventies than I did when I was younger, or whether I’m becoming more and more clueless every day. The truth is somewhere in between, I suspect, but that doesn’t make me rest any easier at night. Like others growing old, I had expected that after everything I had lived through and learned in my life, I would attain a state of Olympian calm and would regard the news of the day with amusement, like a clip from a bad old movie I had seen far too many times. It hasn’t happened to me yet. My late father, in the final year of his life, claimed that he finally found that long-sought serenity by no longer reading the papers and watching television. Even then, and I was thirty years younger than he, I knew what he meant. What devotees of sadomasochism do to their bodies is nothing compared to the torments that those addicted to the news and political commentary inflict on their minds almost every hour of the day."

Edit: Charles Simic is a Serbian-American poet who lived through WWII and saw some really grisly things, some described briefly in the article, hence "after everything I had lived through and learned in my life..."
