Hardwired for Booze

Some studied indicate that man is hard-wired  to seek out alcohol, as our primate predecessors used the scent of ethanol to find food.

Dudley's theory suggests that the alcohol concentration of ripe fruit would have served a purpose for both the fruit-bearing plant and the primate. In tropical forests, fruit can be hard to track down. However, the scent of alcohol from ripe fruits travels long distances, and may have helped primates to find their next meal.
Being attracted to the scent of ethanol from ripe fruits would have been evolutionarily adaptive, enabling the primates to find fruit easier. It was also helpful to the plants, because the primates helped to disperse the seeds in the fruit.
But the gains of eating these alcoholic fruits doesn't end there. Once digested, the theory goes, the alcohol would have stimulated feeding, encouraging the primates to "gobble up the food before anyone else got to it." Humans know this feeling today as the aperitif effect, which you may have experienced if you've ever had a cocktail before a meal and found yourself hungry. Or craved cheese fries after a night out.

I guess that explains why I crave a cheeseburger after a few drinks.  Or an big plate of eggs, grits and hashbrowns down at the IHOP
