For one thing, Master Wheeler, the plural of Cactus is NOT cactus. The
plural of Cactus is Cacti. Look it up before you decide to publish yet
another psuedo scientific paper on the Internet, as though you knew it all.
Now, i will resume reading the rest of what you have written. In that,
in my
lifetime, I have not yet been afforded a scientific backround in the Natural
Sciences as "detailed" as yours, I quite enjoy the reading of it, from your
head to mine, as it were.
