So in the case of you as an adult, your brain weighs 2% of your body weight, but it uses 20% of the glucose.
So you eat food and it goes in two different pathways.
One is to provide you with energy, mostly glucose, and the other one is for building blocks.
Sometimes they can be proteins, sometimes fats, sometimes essential tiny things like vitamins.
So your brain is using 20% of all your glucose, just a little diversion here, in a four-year-old kid, it's 50%.
So you've got a four-year-old kid sitting there doing nothing.
At rest, their brain is using 50% or low glucose.
Then you've got roughly 80, I think it's 80-something billion nerves in your brain.
Now, imagine the nerve like a copper wire.
