At the risk of going a mile off topic here, I wonder don't any of this "vast majority" actually want to understand what they are studying? I mean, we're not talking subtleties here - surely people don't just read stuff like this in these manuals and take it at face value ??? Have people no curiosity whatsoever? (or indeed mistrust of unproven assertions in manuals likely to have been written/proof-read/printed by the lowest bidder)
I suppose I really ought to be old and crusty enough by now to presume they don't teach anything at school any more.
Words fail me.
