Men that consume more than two alcoholic beverages a day could be on the fast track to a permanent blackout – a loss of memory function.

Researchers from the University College London recently studied the drinking habits of 5,000 men over the course of a decade to try to determine what level of impact alcohol consumption has on their brains during middle age. What they found was that men that knocked back more than two boozy beverages a day showed increased signs of memory loss as they got older.

"Our study focused on middle-aged participants and suggests that heavy drinking is associated with faster decline in all areas of cognitive function in men," said lead researcher Severine Sabia.

Sabia says that men that took part in heavy drinking experienced a decline in memory, in some cases, six years before their sober counterparts.
