This is one of the best web sites on the net I have ever visited.It is one that would give the exact answer to ur question.You have to just ask ur question no matter what subject, field it belongs to. Mr Jeeves will find an answer or sometimes give u other sources of obtaining such information. U can use it even to enhance ur knowledge on the topics tought in school and take a leading edge. U can even beat the teacher in that matter!! I have done it the same way. I recommend it to people of all ages as the saying goes, ’’KNOWLEDGE IS POWER AND POWER CAN SAVE YOUR LIFE’’.The only negative point is that sometimes it confuses you by providing u more than necessary information which I think that even experts in that field would not know!!!!!
