Well the nervous system has many functions. It tells us about whether something is hot or cold. And it helps us move. It's a signalling apparatus from one part of the body to the other part of the body. Heroin has the affect of not really speeding up those processes. And if you perhaps are sick and you are also taking heroin, you might not really hear that signal. It's sort of numbed that signal, which means that one of the dangers about taking heroin is you might not react when you really should. You might not go to a doctor because the pain that the body sends, you don't really respond to it. You don't hear it. It's numbed.
