In response to Baycreek - Fred has already answered this , but I might as well add to it since I'm feeling unusually loquacious .
Your doctor may have been wrong in prescribing statins - I would not wish to double-guess his work, but we know more about them today than we did ten years ago. That is the story of science - we learn by doing, and by experimenting. We simply do not have the perfect experiment to show that something is the best possible treatment for every patient with a particular health problem.
On the bright side, science builds upon what we already know (hopefully - and there is an entire separate discussion of this under the subject of the philosophy of science). Science takes something, and improves it - or sees something strange and tries to identify it. Science looks into reports of the paranormal, and finds the microphone under the desk; it investigates bigfoot, and shows that two hours after a person walks in snow the way in which their footprint melts the snow makes it look enormous. Science does not simply accept that things are ineffable.
Even one hundred years ago, this was a new thing. Doctors thought that they would never be able to operate on the heart and lungs, because they could not safely enter the chest cavity. As for brain surgery... crazy talk! Two hundred years ago, most medicine was based upon the body's humors - an idea that our health was affected by the level of blood, yellow bile, black bile and phlegm in our bodies. This concept, and the associated 'treatments' (using blood-letting, emetics, purges and so forth, was around for over 2,000 years. It took that long for people to start testing the theory, and the treatments that were based upon it.
Of course, we have other alternatives today that are embraced by the title 'alternative medicine'. This includes chiropractic, homeopathy and acupuncture, as well as some other forms of quackery. There is, in reality, only one form of medicine. It has been tested, scientifically and rigorously. These 'alternatives' are not really 'alternative medicine', because if they worked they would be medicine - along with other strange ideas that were dismissed, then tested, and adopted in reality-based medicine. The best that these alternatives can do is provide a placebo effect - I think it worked, therefore I feel better.
With that said, I will abandon this thread, and leave others to rage about 'but my chiropractor said...' and 'your doctors are just part of the conspiracy to drug us and...'. My work here is done .
