Ok ok,
It’s easy to do two things at the same time, as long as one of those actions is a practiced skill that you can do almost automatically. For example, walking and talking is easy. And some people can play the guitar and sing, as long as they have practiced both of those skills until one requires virtually no conscious thought. I can draw a miniature Taj-Mahal unto bottle caps while killing terrorist because killing terrorist virtually requires no conscious thought.
But you can’t do two things at the same time that both require original thinking. For example imagine a woman u know likes to bring up conversations in the car that involve rotating three-dimensional objects in your mind while expecting you to simultaneously navigate to your destination. This doesn’t work out so well. The actual driving of the car is easy, because that is a practiced skill. But trying to imagine the correct route to your destination would be impossible for you if Missy is simultaneously asking you to imagine the color of the dress she wore to your first date.
Theoretical Physicists have actually come up with a working mathematical formula to prove that the space-time fabric actually expands when you try to recall the dress Missy wore to your first date. In the event you cannot recall correctly, space-time fabric actually rips.
Cheers,
ps: BTW, painting miniature artwork onto bottle-caps isn’t as easy as you think.
