In search of the silver bullet: regulatory models to address childhood obesity.

The concern over obesity today has evolved beyond an issue of personal vanity to a serious national health issue affecting millions of Americans. Obesity in children is especially alarming. Overweight children and adolescents are at risk for health problems throughout their lives.

Bleedings, purges, and vomits: Dr. Benjamin Rush's republican medicine, the bilious remitting yellow-fever epidemic of 1793, and the non-origin of the law of informed consent.

To the consternation of many physicians, the modern law of informed consent imposes certain constraints on their actions, not least that they respect patients' decisions to redefine at will the scope of care. The consequences of this transfer of power are often a nuisance and occasionally fatal, but always a reflection of democracy's leveling march: Physicians now take orders rather than give them. However frustrating the modern preference for process over result might be, we should ask ourselves-before condemning the law's evolution-about the consequences for patients' health of a more radically democratic practice of medicine.

The effect of abortion legalization on sexual behavior: evidence from sexually transmitted diseases.

Unwanted pregnancy represents a major cost of sexual activity. When abortion was legalized in a number of states in 1969 and 1970 (and nationally in 1973), this cost was reduced. We predict that abortion legalization generated incentives leading to an increase in sexual activity, accompanied by an increase in sexually transmitted diseases (STDs).
