 A new Stanford study just confirmed that men and women's brains do in fact work differently. So it's not your boyfriend's fault he can't find the ketchup in the fridge, he's just built that way. They found that hotspot areas of the brain, including one that deals with memory, actually had different activity in men and women. Other studies have found that women have better verbal based memories, can access them faster, date them more precisely, and recall stories better. While men have better spatial awareness. So I guess we can still let them navigate.
