Scientists think they’ve found the secret to our good and bad habits. It has to do with the pleasure-sensing chemical dopamine, coursing up and down our body’s internal highways. According to an AP report this week, dopamine “conditions the brain to want that reward again and again—reinforcing the connection each time—especially when it gets the right cue from your environment” (South Bend Tribune 1-4-11). For example, you enjoy munching on chips (no doubt a healthful kind). You usually do it before supper, while you’re watching the evening news.

“Return that gift before you get it.” Leave it to Amazon.com to “solve” our gift-receiving woes! The Washington Post this week announced that the mega online mail-order giant has come up with a solution to those gifts from “Aunt Mildred” you’ve never known what to do with—from “The Stallion Stable Music Box” that must have been a beauty on the computer screen but turned out to be a White Elephant under the Christmas tree, to “The Thread and Bobbin Sewing Kit” that, truth be known, will never see the light of day.

Poor Europe—“white Christmas”—bad timing. The wintery blast that has piled a mound of snow across Europe the past few days might have started out a “Christmas winter wonderland.” But the only wonder left now is how to untangle this perfect storm of meteorological and technological gridlock that has turned the continent’s major airports into bed and breakfasts, minus the bed and the breakfast. Nobody’s humming “White Christmas” anymore (especially since that Irving Berlin composition is a distinctly American tradition). No wonder the mayor is so uptight!

Did you see that hastily snapped picture of Prince Charles and Camilla? On their way last Thursday evening to a London gala, the royal couple’s vintage Rolls Royce limousine inadvertently drove into an unrelated street riot and was suddenly engulfed by a sea of demonstrating youth. When the young rioters (who were protesting Parliament’s decision to hike tuition fees in UK universities) spotted the future king of England and his wife inside the automobile, they turned on the limousine, pelting it with eggs, smashing open a window and threatening to who-knows-what!

"12 Daze of Christma$”—that’s how the Boston Herald headlined the story this week of PNC Wealth Management’s annual analysis of the beloved Christmas song. You know the one: “On the first day of Christmas my true love gave to me a partridge in a pear tree.” Two turtle doves, three French hens, four calling birds, five golden rings . . .

MISS YOUR CELL PHONE? I read historian Benson Bobrick’s fascinating Wide as the Waters: The Story of the English Bible and the Revolution It Inspired. It’s the story of two English reformers—John Wycliffe, the brilliant Oxford scholar and Bible translator, remembered as “the Morning Star of the Reformation”; and martyr William Tyndale, whose English translation of Holy Scripture led to the King James Version and made the English Bible (next to the Bible itself) “the most influential book ever published.”

Jesus just grew bigger! Ever since last Saturday the small Polish town of Swiebodzin has been high-fiving in celebration, believing they have just created the largest Jesus in the world. It’s been the life dream of their 78 year old local priest, Sylwester Zawadaki, to craft the world’s largest Jesus statue. And it looks like he just succeeded.

Another election wrapped up, another terrorist plot averted. While I’m not suggesting this week’s two biggest headlines have any connection, have you ever wondered how proactive God is in the life of our civilization? He probably doesn’t keep an electoral scorecard of favorite politicians, and he certainly isn’t the author of evil conspiracies. Nevertheless, could it be that he is personally, actively very much engaged in what goes on around this planet? Let me explain.

Too early to be thinking about Christmas? Not if you were hoping to purchase the fastest and most expensive Porche ever built—the 911 GT2 RS. It just sold out less than two months after debuting. Price tag? $329,000. Merry Christmas and a big red bow tied on to the 131 Americans who bought it.

“Savior Siblings” was the newspaper headline. Molly Nash is sixteen years old now—and very much alive. But in 2000 the promise of any future at all was doubtful. Molly was born with a severe type of Fanconi anemia, “a blood disorder that almost always results in leukemia by the age of 10.” Her only hope a bone marrow transplant. And the optimal transplant donor needed to be a sibling with genetically identical tissue. But Molly was an only child. Until Dr. John Wagner—a bone marrow transplant expert at the University of Minnesota—suggested a brave, novel protocol.
