So you take all "science" pubs. at face value? Asprin prevents heart attacks/no it doesn't- it's bad for you. The Adkins diet is the greatest thing since the club - no it isn't, Humans are the greatest cause of global warming - they are largely insignificant....I could go on and on. How often do we hear such and such, only to find out later a "new study" refutes what we've been force-fed for a decade or three...
Color me sceptical - I filter. No, it isn't "supposed" to be necessary- but it is... big business, politics, grants, and funding as it is....
Follow the money/bias- and take the appropriate off-set. There is still often "nuggets" to be had. Either gold or poop.....
