The longer a woman's fertile life (the interval between the menarche and the menopause), the more likely she will develop Parkinson's disease.

Aspiration of a foreign body into a child's lungs is a potentially fatal event, says a report from the University of North Carolina, which has been collecting inhaled objects since 1954 (Southern Medical Journal 2004;97: 434-6). A comparison of 26 objects recovered from the lungs …
