Tobacco companies poured nearly $47 million into defeating Proposition 29, a $1-a-pack tax hike on cigarettes, but the measure was narrowly leading in early returns Tuesday despite the hard-fought campaign. The tax increase would raise $810 million a year for cancer research and smoking cessation programs, and it would give California -- which currently has a lower tobacco tax than 32 other states -- the 16th-highest cigarette tax in the nation. … The vote would be a huge win for the public health groups that sponsored the measure, including the American Cancer Society.

Regular and moderate exercise most beneficial for cardiovascular health

Micah True, legendary ultra-marathoner, died suddenly while on a routine 12-mile training run March 27, 2012. The mythic Caballo Blanco in the best-selling book, Born to Run, True would run as far as 100 miles in a day. On autopsy his heart was enlarged and scarred; he died of a lethal arrhythmia (irregularity of the heart rhythm). Although speculative, the pathologic changes in the heart of this 58 year-old veteran extreme endurance athlete may have been manifestations of "Phidippides cardiomyopathy," a condition caused by chronic excessive endurance exercise.
