It is a fact that men are less able to multi-task than women.
It's a genetic throwback from our cavemen ancestors - the woman would tend the cavev, look after the children, prepare food, and keep an eye out for preditors, which is a multi-taskling format that their descendents have inherited. That is why a woman can see car keys that are sitting three feet away, while the man cannot.
Cave man on the other hand had one task - to hunt and provide, which is why he focuses on one individual task at a time and why his inherited distance vision, from years od scanning horizons for something edible, is better than his partner's, and he often misses things which are in close range.
It's all part of what makes us different - to be appreciated and enjoyed - when possible!
