WOW! It is so hard to argue with the invincibly ignorant. But it is quite incredible that you believe that Isaac Asimov, a Professor of Biochemistry at Boston University for a good part of his life, failed to comprehend the most basic of physical laws.
And as for AIDs being "no big deal", let me know when YOU get it ( perhaps you will volunteer for a study, and be infected) and tell me again that it is "NO BIG DEAL"!
What a clown you must be- I'm very glad I don't have to deal with you in real life!!!
