Dear Alex, thank you for your message. Of course people have every right to be concerned, but their concerns have to be based on something tangible, otherwise they are just conjectures. Science is not a perfect system, but it is the best approach we have so far. And the nice thing is that if you do your research and come up with better results, you can refute those studies too. But you can’t refute something just on the basis of hearsay because if you do that, then I can come up with any theory and raise a concern on anything under the sun.
