Links this week:

  1. Skip your annual physical.

  2. The phrase “Statistical significance is not the same as practical significance” is leading us astray.

  3. The ineffectiveness of food and soft drink taxes (although not all calories are the same). The latest extension of the nanny state - banning junk food from playgrounds. And a new book worth looking at - Government Paternalism: Nanny State or Helpful Friend? (HT: Diane Coyle)

  4. Marijuana in Colorado - no surprise that the most grandiose claims of both sides haven’t come to fruition.

  5. Even more on lead and crime.
