  • A dentist says prophylactic removal of wisdom teeth is a bad idea. “Ten million third molars (wisdom teeth) are extracted from approximately 5 million people in the United States each year at an annual cost of over $3 billion. . . . More than 11000 people suffer permanent paresthesia—numbness of the lip, tongue, and cheek—as a consequence of nerve injury during the surgery. At least two thirds of these extractions, associated costs, and injuries are unnecessary, constituting a silent epidemic of iatrogenic injury.”
  • Duke University trustees defend endowment secrecy in funny ways. “David Rubenstein ’70, the Trustee chair, [says] Duke can keep a student’s grades secret — available only to a few administrators — and the principle is the same with Duke’s money.”

    “Duke can keep a student’s grades secret — available only to a few administrators”: this is a feature of American life that I don’t understand. My university results were published in the newspapers. Is it just another example of American talk of free speech and freedom of the press being baloney?

    The removal of wisdom teeth also affects the aesthetics of your face.

    With my family, there was a noticeable difference for the worse after the wisdom teeth were taken out. The cheeks have this sunken look.
