We all know that loud noise can damage your hearing - but it seems not enough noise can also impair it. Consequently, people in cities have better hearing than those in quiet villages.
Researchers at the Universtity of Giessen in Germany spent over a decade testing the hearing of some 10,000 people. As expected, people exposed to very loud noises as part of their jobs, such as construction workers, had poor hearing. But those living in quiet rural areas had hearing not much better. And people, including airline pilots or orchestral musicians, who encoutner constant noise at work, could hear very well. Firefighters, whose lives can depened on sounds, had exceptional hearing.
The team concluded that continual exposure actually "trains" the ear to tolerate it; it is sudden, extreme noise that does the damage. Which would explain why Asian villagers, whose quiet lives are punctuated by occasional firework celebrations, have the worst hearing of all. » Continue reading
I felt that the people commenting on this blog were not really getting their due. The NoFollow attribute which comes by default with the Blogger templates just stifles the incentive to comment.

Tricks to get more done in less time, from the clients of US career coach Terry Kozlowski:
Looking for an after-dinner snack? Try cereal -- it may help you lose weight, say American scientists. Of 58 overweight nighttime snackers, half ate a 150-calories bowl of cereal and low-fat milk at least 90 minutes after dinner; the others ate as usual. After four weeks, the cereal eaters had lost one kilo, and ate 140 calories less than usual after dinner. The others ate 85 calories more. The study was funded by the Kellogg Company, but the researchers say the type of cereal doesn't matter. What does: sticking to the serving size.

An increasing number of children are allergic to some kind of nut, with potentially fatal consequences. About 20% seem to "grow out of" their allergy in time, though there is a chance the allergy may come back. Now scientists have found this chance can be lowered -- by eating peanuts.
Scientists can't stop finding health benefits for tea. Tests at the University of Newcastle upon Tyne, UK, suggest that tea, and particularly green tea, may improve your memory and slow the onset of Alzheimer's.
