Just to add to the possibilities. I read recently that there are some ethical issues in the USA with the possible use of epigenitic drugs. I think it was bloomberg but haven't been able to find it. This is a topic being discussed for sure. Where do you draw the line when dealing with Genetics. This may be playing on the FDA's decission. Just food for thought and any time I put myself out there Don makes a fool out of me, so maybe we will get approval soon. lol
