Slide 60:

Now the human body is made up of cells, we all know that. So is the brain. What is actually astonishing is that a child is born with 100 billion brain cells. Perhaps this is why they say we can lose a few here or there and be OK, but it doesn’t mean we can lose a lot of brain cells. These cells are not connected in networks when a child is born. The networks formed by brain cells are crucial to, among other things, allow thinking and learning to take place. A few slides ago, when I said the only thing important to me at this point with your children is cognition, if you can get the brain working, then everything else can be helped with therapy and with other aids. If that brain is still sitting at idle, you’re not going to win in the long run, except in very rare, very unusual circumstances.
