From a
CNN article about a new heroin blend popular with teenagers:
"A double whammy -- you're getting two downers at once," says Dallas police detective Monty Moncibais. "If you take the body and you start slowing everything down, everything inside your body, eventually you're going to slow down the heart until it stops and, when it stops, you're dead."
When your heart stops, you're dead. Brought to you by the Dubya School of Public Speaking.
