"Life is short, make a fools of yourselves while you can!" - The Dormitory Boys
It is a funny quote indeed, which is shown as their slogan on the top of their blog page (see link at the right-hand column).
Life is short indeed, it will be shorter if you have to spend it as a prisoner. Your freedom is taken away from you and you cannot go anywhere but inside the prison only. Your life can get even much much shorter if you have to face a firing squad or be hung due to your crime, for instance smuggling heroine.
Some people are consciously committing a crime like drugs dealing, due to the good money they can earn, however they do not realise if they are wasting their lives. Once they get into this chain of drugs dealers, they can hardly get out safely. It is either they get caught, get killed by their rivals or be addicted to drugs. Whichever it is, it's a wasted life.
