Well I read it again and I think I'd have been patronised if I'd read it from someone else...I think you're just being a bit too gracious.
I think my main point is that for your average Joe Bloggs, you're in the gym and doing your stuff, you're going to have a drink when you get thirsty. You're never more than a few feet from your water bottle and you're not going to wait until you're dying of thirst.
Having the 100% optimum hydration level is going to be a deal breaker for a top level olympian, but otherwise, the worst than can happen is that you feel a little bit knackered a little bit more quickly. It's not going to have any great overall net effect on people like me or the 99% of the population that the advetising is actually aimed at.
I worry that the danger is people read and believe the advertising pumped out by water / sports drink manufacturers, believe it, and shell out loads on fancy drinks.
Absolute worse case scenario, they drink too much and damage themselves. More irritating case scenario, people spend too much money on crap and make a drinks corporation richer.
I think that's my main beef....when people perpetuate a myth about 'advanced hydration' (or anything else) without discussing it or even considering the fact that it may have been started by someone with a vested interest....
EG my favourite example of this kind of crap is the "SCIENTIFIC FACT!! TEA IS HEALTHIER THAN WATER!!!"*
