"Can't, people with M.E. aren't allowed to donate organs, blood or bone marrow" I suppose it's a mild improvement on the days when medics didn't even believe ME existed... I think the reason may be that there's no one clearly defined cause and no specific cure, and no real way of knowing how that would combine with the immune-suppressants that have to be taken to keep the organ from being rejected? Roll on the days when we can each grow our own spares in a glass jar.
