Why does thinking take time?
gpt
Thinking is a chemophysical reaction in your brain. Your brain neurons function through ionic potential. They use electricity, created by chemical reactions, to move information from one part of the brain to another, and eventually to your muscles (although it is not quite the same as electricity flowing down wires).  
  
Simply put, the reactions are not instantaneous. Millions of nerves have to fire, and this results in a thought. Through the use of modern sensing technologies we can actually see brain activity, and time how long this takes.
