Did I say I was a great scientific researcher? I, like you, parrot others who have done field and laboratory research in much of what we post. The reason there are different fields of study is because no one is smart enough or has enough time in life to learn even a extremely, infinitesimal, small percentage of all available information.
You tend to attack the messenger because you don't like the message.
