Indigent dental care in Virginia: An update.

I wrote a lengthy piece on the state of indigent dental care in Virginia a few years ago. It continues to be read regularly, and I get often get e-mail in response to it. A few days ago reader “LCS” e-mailed me the following: I just recently went on an archives hike and came across …

Friendship extends lifespan.

For the New York Times, Tara Parker-Pope explains that friends are good for your health: Last year, researchers studied 34 students at the University of Virginia, taking them to the base of a steep hill and fitting them with a weighted backpack. They were then asked to estimate the steepness of the hill. Some participants …
