Even though I am nearly deaf, I seem to be gifted with a kind of inner hearing which enables me to detect sounds and noises which the ordinary person does not hear.
Thomas A. EdisonThe injurious agent in cigarettes comes principally from the burning paper wrapper. The substance thereby formed is called "acrolein." It has a violent action on the nerve centers, producing degeneration of the cells of the brain, which is quite rapid among boys. Unlike most narcotics, this degeneration is permanent and uncontrollable. I employ no person who smokes cigarettes.
