My dad got snookered by his friend into attending one.... he had
to pay $15.....
Luckily, he didn't buy any of the bullsh*t in that seminar.....
and I don't think he's on speaking terms with that friend any
more.... 
Honestly, I'd attend one if I was invited to it. It would be fun
to introduce chaos into the seminar by pointing out all the
scientific fallacies of 'alkaline water' and 'magnetic
bangles'.

go ahead and try ... they haven't chut power yet .....don't
underestimate them ... they can talk black into becoming white
....
look, these are the same bunch that managed to hoodwink grannies
and grandpas out of their retirement funds, undergrads out of their
parent's money, and got a battalion of suit wearing teenagers
swearing fealty to their cause ...
what's a few puny laws of physics ....
