Actually, I just don't place my faith or my well being in the hands of others as casually as you (or many others) do.
Casually? Pfft.
I'm glad your so impressecd with NICE and the concept of dosage "ranges".
As with engineering there is always a certain tolerance to work within. Why should the human body be any different?
The reason there are ranges is because people are different, what might be enough for one person might not be for another of the same body weight.
The point is it completely blows out of the water your initial claim, at least for the UK.
It still looks like a way of dumbing down a concept of dosage control to me.
NICE guidelines are written by panels of experts who trawl through research papers and put together more readily accessible documentation for people on the front line, who for the most part really don't have the time to spend months at a time getting the latest research into a given medicine and weighing it up against previous research any time they want to give someone a shot.
And, no, I don't think the standards of my education were that low. Most of you wouldn't have been able to pass those courses. I had a GPA of 3.89 at the time and still felt relieved to get out of Physiology with a low B.
You might want to go back and read what I actually said, I didn't aim the comment at you, in fact I'm fairly certain it was aimed at your medical profession, again, if your claims about the US system are correct. Which I'm sorry to say I really doubt, since a lot of the papers that are sourced to put together NICE guidelines come from the US.
