Different Thoughts!

I was thinking that there are many spiderman's movies and there are many spiders in old houses. How this thought came into their mind that if a spider bit a man then he could have extra ordinary powers. When i saw this movie i also thought that may be one day a spider will bite me and i would get extraodinary qulities.

Second: you must have seen that some spider are produced for special work. Some spider are useless which we see at our homes some time who not only eat some animals but also leave a spot on wall.
