Don't get it.

Sometimes difficult to understand the attitude of "experts" towards what seem to be common-sense decisions.  It has been suggested that those who are terminally ill and who agree, should be able to be treated with unproven drugs.  What's the worst that can happen?  They're dying anyway - difficult to see how things could be any worse than that, and it's possible that the drugs might be beneficial, and certainly the exercise will provide data which would otherwise be unavailable.  And yet, a respected scientist has said that such an idea is "too risky" and might end up doing harm.  To whom? Can't really see how you can do any great harm to those who are already dying. I would certainly volunteer to be a guinea-pig in such circumstances - what would I have to lose?
