	Description:		A second man has effectively been cured of HIV, but scientists are reluctant to call it a cure. That's because the method is expensive, painful, and in some cases deadly. But the so-called London Patient might hold clues about the best way to cure the virus in the long term. The answers seem to lie in a HIV-resistant gene that emerged during the 16th century plague. So how much do humans actually need disease in order to keep evolving? Is it possible that we've wandered into a genetic cul-de-sac, and stalled the evolutionary process?
