The ice packs should be used on a schedule of 20 minutes on and 5 minutes off, continuously, as long as the patient is not sleeping or eating. After 24 hours, ice generally has no beneficial effect on the swelling, but many patients find it to be a helpful adjunct in reducing pain.
The average score on most IQ tests is 100, and approximately 68 percent of all people score somewhere between 85 and 115. For those who fall below 85, scores are often classified in the following way: 1 to 24 - Profound mental disability. 25 to 39 - Severe mental disability. 40 to 54 - Moderate mental disability.
The comparable figure for whites would be about 16 percent. Total black population with IQs over 115: 800,000. Comparable figure for whites: about 30 million. If blacks had the same IQ distribution as whites, the black total would be over 5 million. The data are even more depressing on the downside. An IQ in the 70-75 range, which many psychologists would label borderline retarded, implies a life that is guaranteed to be short of opportunities.
