That immune guy is probably tested on loads in an attempt for an alternate cure, I wonder how many people are immune...*
money is the cure, lots and lots of money, liquidised, compressed, and injected into the blood stream.
you have to think about the nature of science. Nothing can be proven without an experiment. the idea of smoking being bad or you has no real evidence. they haven't got a group of people and told them to smoke or not for a set period of years. why because it would be inhuman. Likewise with aids, some people believe circumcision can protect against aids, but without an actual experiment wont know. killing 100 people to cure aids is probably worth it considering how much it will continue to kill.
