Now, I haven't read/watched the link, but just ADD thing has me going on another rant:
In recent years, studies on 'disorders' such as HADD, ADD, and dyslexia are yielding results that young kids won't like: they are being proven more and more to be 'mythical' disorders.
A couple points against ADD is that, by definition, it is a lack of attention - so what is it called when someone has too much attention (i.e. you can't go under if you can't go over) - and what is considered to be a 'normal attention span' anyway?
H/ADD is most prominent in childhood, and children are naturally curious - it's how we survived for hundreds of thousands of years (sorry all you creationists out there - get with the picture!) A by-product of curiosity is the habit of shifting focus from one subject to the next quickly and sometimes spontaneously - i.e. what some would term 'classic ADD.'
Dyslexia, on the other hand, I personally (and from my own personal experience) would immediately class as, how the English say, 'bollocks.' Can everyone in this forum read music? If not, does that mean you are 'musically-dyslexic'? Probably not, it may just mean you either haven't learnt how to read music, or you haven't learnt correctly. English isn't taught in British schools (don't ask me. . .) and dyslexic is rife here. In 15 years of living in Georgia, I met maybe one or two 'dyslexic' people. In 6 years of living in England, every-bloody-body and their best friend is dyslexic. Seriously. Most people will, admittedly, tell someone they are dyslexic because they can't actually be bothered to read. More than you think, as well.
So if anyone thinks they may be suffering from any of these 'disorders', just forget about it, pick up your axe, and play away!
oke:
