I have chosen to do sports for fun, not drugs. Drugs are a form of escape for people who can't or won't choose life without drugs. It's difficult to avoid alcohol though. Technically alcohol is a depressant of the Central Nervous System (CNS). Sorry, now I'm rambling. Time to do something fun... Choices.
