A longer shelf life may be yours if you stock that shelf with the right amount of alcohol

Medical studies, as we have pointed out several times in this blogosphere, can be even less reliable than weather forecasts. Medical researchers frequently contradict one another until their credibility is lower than a shifty guy trying to peddle you a supposedly expensive watch on a Manhattan street corner.But medical studies do perform one important function — they can stamp our lifestyle choices with an official imprimatur.For instance, researchers in Italy have just released a study that says moderate drinking may lengthen your life while too much booze will shrivel up your liver until it resembles Joan Rivers and then kills you.Granted, this study seems to be playing rehashed chords. But the Italians, likely a thirsty lot, have rather liberal criteria on what constitutes moderate drinking.They claim up to four drinks per day in men and two drinks per day in women can reduce the risk of death by 18 percent.Four drinks a day? That’s a lot to swallow. But if it can help me live as long as Methuselah, it won’t take a lengthy negotiation with my inner self to make me drink to that. Indeed, this report has a tide so strong it should suck in legions of drinkers. Then again, after four drinks our willpower could be drowned in shots. And we soon could find ourselves on a gouged and pitted road to an early death as we take the fifth.
