What I like about HV is his objectivity. And that's BIG. Objectivity is the single biggest obstacle when it comes to discussing health today and you very rarely come across someone capable of it.
Of course you need an incredible amount of knowlegdge to achieve it and HV has that. He seems to be the most 'conventional' alternative person out there and this is what makes him invaluable. It's not all airy fairy stuff, it's backed up by evidence in most cases. Also when he mentions rife machines and 666hz and al that, you know he's telling the truth.
I do disagree with him over the Amalgam issue as the effect their removal had on my libido(semen production) was staggering (definately no placebo that) but even his theory on why he thinks they are not a threat health wise is based on a sound logic, so I can overlook that and still trust him on other issues.
