New knowledge got, but all dark side de... don't want to
share... 
Ah yes, learn about a new drug while reading up on drug abuse. PCP
was the drug name. Supposed to be a good invention to numb people
during operations, but the side effects were bad. Later, people
found out about it, and abused it. Sigh....
And all these are too chim for me.... nowadays not reading up much
on bio stuff, no time.
