Is it more accurate measurement, or other reason? In a text book, it said it is related to the size.

My cousin believes that by having a "Huntsman" roaming around his house that he is controlling other pests. He believes that the huntsman will eat the majority of other smaller spiders including the nastier redbacks and white tips that we have in abundance here in Australia.

Is he kidding himself or is has he actually discovered an effective non carcinogenic way of controlling pests around the home?

A church right behind us has a tower that seemed to be home to many, and last fall it got some damage in a storm. Since then, some have gotten into our house & always dive over my head - once when I was on the computer, once while watching TV, and last night while in bed...scary to wake up at 2 am to the sound of wings over you head! My boyfriend caught it under a towel & threw the whole deal outside, then said the bat 'smelled terrible' when he came back in. Now I am worried; could they be sick & dangerous? This is an old (1918) big house, I doubt we can stop them from getting in, but what can we do to discourage them? This is in east central Indiana & are most likely Big Brown or Little Brown bats. please help!

I understand the theories behind why we yawn -- I did look up similar questions in Yahoo!Answers. :-)

But I always yawn at two stange instances: When I am very nervous (an unfortunate example is job interviews), or when I exercise - no matter what time of day.

I don't get it. I have a great diet, in fact I regularly see a nutritionist, and I work out six days a week. I am not overweight, but certainly not skinny. I'm in my 30s. I get a good amount of sleep each night. I've just got too much going on to ever say I'm bored.

Any theories on why I would yawn when I'm nervous and when I exercise?
