I quit in my early thirties after two of my best friends were killed by a drunk driver. That and quitting smoking at the same time were the smartest things I ever did, and over the last thirty years I've got to watch as those family and friends who didn't paid the prices you got to pay for living life for your bad habits. It's just plain stupid, drinking away the love of one's family, going to prison for a drug or a drink, or ending up in the liver ward or an insane asylum, or dying fifteen years early for a mouth full of smoke. Glad I missed that ride. The needle and the damage done.
