But only momentarily. Even when a ball is going out of bounds it's not because of a sabre tooth tiger being on our tails but because of a fear of loss. There are thousands of hormones in our bodies ready to be released by our sensors to activate various reactions both external and internal. Virtually nothing is done unless it is triggered by a chemical reaction in our brain - the power source for the electrical energy required. If your spinal cord were cut there is no possible way your conscious or subconscious mind can make the legs operate.
Some diseases do the same thing.
Think of a number between one and ten. In the recesses of your mind you can automatically bring that number to mind from a storage long long ago put down for just this purpose. Once learnt never forgotten - its all stored in the mind, the subconscious mind. A person, having driven a motorcar for years, drives subconsciously - ever mentally alert for visual or sound danger signals. Taken in or out of context this statement is nonsense.
