According to the Jan. 20-29 poll, 73 percent of American adults said it was "very likely" or "somewhat likely" that they would let their sons play organized football if they showed interest in the sport. The poll also showed the interest in letting children play football declined with the respondent's education level and with age, and that whites were less interested in football for their children than minorities. For Christopher Rice, a 35-year-old transportation worker in Chicago who was in the "very likely" category, the intrinsic value of playing a team sport far outweighed any risk of injury.
The first solid evidence that smoking causes cancer came in the 1950s, followed decades later by revelations that "second-hand" smoke also harms health. In mice, at least, exposure to these toxic leftovers causes lower infant weight and alters counts of blood cells associated with the body's immune system, they reported in the Nature journal Scientific Reports. "Evidence is mounting that the residue lingering on indoor surfaces could be just as harmful -- if not more -- than second-hand smoke," said the Lawrence Berkeley National Laboratory, which took part in the study.
