There was a time I raised a question why some people are not stung or bitten by mosquitoes. I raised the question at Yahoo answers because in our entire married life, my wife was never even bothered by mosquitoes. To cut it short, only one made an answer and it was quite a dumb one. The answer suggested that my wife could have been putting on an insect or mosquito repellant! Would I not know that? Some people who make answers to questions probably lack logic or common sense.
I waited for a month to get a sensible answer but there was none. It came to my mind that there was really no one that goes to Yahoo Answers with good general knowledge. My general knowledge is also not that good so I only put answers to those that I specialize in like cars, marketing and management. Anyway going back to my question there was no any answer after the first. I learned about the answer accidentally while watching a television documentary why some people are not stung by mosquitoes. Many answers to questions can be learned watching television especially Discovery Channel.
