TV is based on someone's agenda. they might tell you something doesnt work if it does, that way they may see more positive tests. I dont know, all depends on who's financing the project.
Ive also seen myth shows that said sucking on a penny wont help you pass a breathalizer test after drinking, yet I tried it and it worked wonderfully. So I don't know what the deal with the myth shows are all about.
I dont want to say my suggestion is 100% accurate all the time either, but I just felt i should defend it since Stabber said it doesn't work.
