Query: disappointed from the whole series

I am more than disappointed. The content of the DVD is absolutely of no help. Says nothing more than trivia. And people like me paying a fortune to collect dvd's like that, waiting them eagerly, just to find out that some guy with no scientific credentials, appearing on the screen just to sympathize (which i do not doubt, sincerely) and say that we should eat healthy foods and get a good sleep, after repeating a hundred times:"i will reveal to you my secret formula, 100% guarantee blah,blah,blah'. Really, bying this dvd was something i have clearly regreted and undermined my intelligence.
