To those who are budding scientists, and do their own research and experimentation, while waiting for the FDA and all those highly paid researchers to get some results in the battle against PD, I remember this little poem: Johnny was a scientist, he isn't one, no more, What Johnny thought was H2O, was H 2 S O 4! I realize this is not the exact wording. Also, I am sure that H2O is water, but not sure what H2SO4 is, but I am pretty confident it is explosive or poisonous. I am also quite sure Johhny is not longer among the living! Corrections will be appreciated. [log in to unmask]
