When I mentioned some of the arguments against social-host laws at the San Diego County Alcohol-Policy Panel, DiCiccio offered another reason that kids shouldn't drink with adults: alcohol could hurt their developing brains...
That would be one way to tell this story--but the truth is more complicated. At the Berlin Wall, guards fired live ammunition, and still an estimated 5,000 people managed to cross. And why shouldn't the fence be a complicated subject? Everything else about immigration and border security is complicated. The border has become the rice, or maybe the potatoes, of American politics; it goes with just about everything on the menu. It's an economic issue: Are illegal immigrants taking jobs from American citizens and driving down wages? It's a health-care issue: Do uninsured aliens...
...lots of preclinical trials, the human is the ultimate animal model - and sometimes a potential downside to a new compound is not identified until it gets to a human. We often hear you can't give aspirin to cats because it's toxic to them, or you shouldn't give chocolate to dogs. Chocolate, which is very safe in humans, is not safe in dogs. But when you go back and look at how many compounds fail before they ever get to humans, [it's clear] animals do play a really important role in at least giving early signals...
...sizes have ballooned, or the fact that simple physical activity has been largely eliminated from the daily lives of children, who ride in cars where their grandparents might have walked and entertain themselves with an array of sedentary electronic pastimes that didn't even exist a generation ago. It shouldn't be surprising that many overfed, underactive kids lose the battle with their weight. "The environmental factors are much more compelling toward obesity than they were 30 years ago," says William Dietz, director of the division of nutrition and physical activity...
There are a lot of ways the push-pull between simplicity and complexity is being explored and explained. Consider how babies learn to speak--a job so complicated that by some measures they shouldn't be able to do it at all. By the time babies are 18 months old, they have a core vocabulary of 50 words they can pronounce and 100 more they understand. By their sixth birthday, children have a working vocabulary of 6,000 words--meaning they've learned, on average, three new words every day since birth. Mastering conversational English requires about 50,000 words...
