President Obama spent his first year in office trying to prevent the collapse of big financial firms, and stabilize the national economy. Now, he is taking a more populist approach--focusing on the day-to-day issues that create money woes for many families.

"We have just come through what was one of the most difficult decades the middle class has ever faced—a decade in which median income fell, and our economy lost about as many jobs as it gained." The president spoke at a meeting of a White House advisory panel set up to study the problems facing the middle class and to propose solutions. Among the ideas embraced by the administration are steps to cut the costs of child care for working parents, and help them save for retirement.

He has pointed out that our thirty-two teeth evolved in the past to deal with a much tougher diet than we have now. Our ancestors ate tough gritty food, and so they needed many teeth. Our teeth, however, do not have to cope with such a diet, because we eat much softer food. Unless, therefore, we are prepared to eat the diet of our ancestors, we should get rid of some of our teeth. Instead of thirty-two teeth, it would be better if we had a well-spaced set of twenty to twenty-four. This would force the rest to work harder and make them more healthy.
