Time flies when you're having fun, so if you don't want your life to pass you by in the blink of any eye, try being miserable. Death row-ers, allergy sufferers, valedictorians, trapped miners, parapalegics, anorexics, the homeless and child laborers don't complain about life moving too fast.
Time also flies when you're smoking uppers, so try sticking to barbiturates and bourbon.
