Some will always put a negative slant on things. Some apply erroneous initial experiences for the remainder of their lives. In that case,60 years times one is one. To blanketly say obviously that everything has been learned about something because it has existed for 200 years is nuts. If that were the case,we would still assume the earth was flat! Where is the proof of conclusive sampling of the claims? No matter what the self appointed Nawab says it still has to be proven. My one post so I have to be careful what I say here.
