The oldest evidence of the use of bows to shoot arrows dates to about 10,000 years ago; it is based on pinewood arrows found in the Ahrensburg valley north of Hamburg. They had shallow grooves on the base, indicating that they were shot from a bow.
Sudden infant death syndrome. Sudden infant death syndrome (SIDS), also known as cot death or crib death, is the sudden unexplained death of a child less than one year of age. Diagnosis requires that the death remains unexplained even after a thorough autopsy and detailed death scene investigation. SIDS usually occurs during sleep.
The standard seeks to prevent the risk of deaths and injuries from falls or entrapment due to parts failure, dislodgment, or poor maintenance or assembly of the crib. The CPSC published a new standard in 2010, which improves significantly the safety of full-size cribs.
