Back to the Past

Scientific studies have proved the lag between actual events and when our brains process them is about 80 milliseconds. Use one 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. It understandably takes more time for the signal to travel up your nerves from your feet to your brain than from your nose. The reconciliation is simple: our conscious experience takes time to assemble, and your brain waits for all the relevant input before it experiences the ‘now’.
