We actually live about 80 milliseconds in the past.
because our brain takes 80 milliseconds to process information.
everything you are experiencing right now, actually happened 80 milliseconds ago!
Use one your hand to touch your Nose, and the other to touch one of your Feet, at exactly the same time.
you will experience them as simultaneous acts. but it takes more time for signal to travel up your nerves from your feet to your brain than from your nose.
