&#62; Humans are incredibly awful at multitasking.<p>On the contrary, we excel at it by pushing things 'down' when we have mastered them.<p>For instance, driving and talking to a passenger, walking and thinking about something and so on.<p>We are so good at it that most of the time we don't even notice any more how many things we are doing at the same time.<p>The only time we are <i>not</i> multitasking is when we are really concentrating on something difficult, usually problem solving or learning a new skill.
