What an incredibly ignorant and oblivious thing to say....
All research, no matter how it is conducted or interpreted, remains the cornerstone of human learning, as long as all of its criteria and parameters are carefully laid out and accurately presented... We must judge research for what it's worth, and only that, but to say that it means NOTHING is to say, "I GIVE UP... WE ARE ONLY GUESSING AT EVERYTHING".....
If we listen to you, we might as well ask the bum down the street his about opinion on Amalgam toxicity and it's effect on human health...
