...motorists who have been worried that the belt itself might cause injury, there was reassurance from both California and a Cornell University study: in only a fraction of 1% of accidents did belts cause injury, and even when they did, there was always the possibility that without them the injuries would have been worse. As for the hazard of being trapped by a belt in a burning or submerged car, the National Safety Council says: "The belt greatly improves your chances of survival. It helps to keep you conscious, so you can get clear of the car." Free to Squirm...
Virologists, pediatricians and public health officials have worked out a compromise.

The "GG" has staved off fever in all but about 20% of children already double-vaccinated and has eliminated the rash in all but 3%. Most important, the GG does not keep the children from developing enough of their own antibodies to give them lasting protection against natural measles...
...makes a convincing case for the decision. Each mode, says Shea, was broken down into major elements, starting with takeoff from the earth. To each element was assigned a number expressing its relative hazard as accurately as possible. A very safe element, for instance, might have been given the fraction .9998, while a very dangerous one might have gotten .75, meaning that it would probably fail one out of four times. After all the hazard numbers, from take-off to return, were multiplied together, the result represented the hazard of the whole mode. In the final reckoning, LOR looked best...

Without UHF we wouldn't get educational stations into more than a fraction of the communities that want and need them...
