From a conversation I had with a friend yesterday (highly paraphrased):
Friend: I've been reading your blog lately. What's the big deal about these XMRV studies?
Me: Remember how last year, someone discovered a link between the retrovirus XMRV and ME/CFS? Now other scientists are trying to figure out if the link really exists.
Friend: What if it does? What difference would it make?
Me: Because if there's a link, then they can help ME/CFS patients by treating the retrovirus. Like with HIV. Y'know how AIDS used to be a death sentence? AIDS is still something you really don't want to have, but now if you're on the retrovirals you can live with it.
Friend: But is there a treatment for XMRV?
Me: No. But if there's definitely a link, they'll have a reason to develop one.
