So now you can turn skin into blood?

A Canadian study published on Sunday claims that stem cell researchers have found a way to turn a person's skin into blood. What happens is that cells from a patch of a person's skin are transformed into blood that is a genetic match, and then you'd be able to make your own blood for a transfusion. However, I'm not sure if Jehovah's Witnesses, who already reject other people's blood for religious reasons, would turn their own skin into blood. And personally, I think that's a ludicrous idea and they should actually study it more.
