Hi Eaoz - sure, and as I continue my new journey into this corner of the world I'm confident I'll find out more about the various levels, figures, and so-called facts, and it's through people like yourselves with your knowledge who are helping me do that along the way.
Your profile does have plastered all over it that you're a skeptic though, so that suggests to me you're going to be skeptic about everything, and the way you mention 'scientific evidence' leans me towards you're a believer in what 'the establishment' say when 'the establishment' are very much controlled by corporate influence, for example just take a look at lobbying in the U.S.
So, in conclusion I thank you for your information as you're right as far as I know, it's just one side of the argument/scenario, but that doesn't mean they're right or wrong, quite often things change, for example the education system set up for the industrial age is no longer fit for purpose but is still here, the same goes for things like the pharmaceutical industry whose system means that things like B12 aren't focused on as much as they make lots of money out of other things. No big conspiracy theory there, it is what it is.
As for scientific method, have a watch of some of the people like Steven Jones who apply it to 9/11, I'm very much a believer in the scientific method, after all, I've been hacking computer code for the last 34 years since I was 9!
Thanks again, I'll add a "not scientifically proved" star to that figure!
