Now this is very interesting indeed. Personally, I would start doing tests like these on people right away, but on a very small scale, but only to volunteers that have been informed and prepared.
I never was fond of how promising discoveries come around one day, and are almost never heard from again because further experimentation isn't done for nearly a decade. I understand that those doing the research want to make sure things are done right, but sometimes, I think it would be better just to take a chance and try.
But I like this article very much. If you come across anymore information on this subject, please let me know.
