The brain’s nerve cells (neurons) connect with each other at arrays of synapses. Try to imagine all the stars in our galaxy. There are 1000 times more synapses in each person’s brain: 125 trillion.

Yet there’s still plenty of extra room in your skull. The brain contains 60% fat, quite a bit of which is cholesterol. Ten times more numerous than the neurons are the glial cells. They help coat the neurons with insulation and help them construct more synapses.

Emily Dickinson said, “The brain is wider than the sky”. Leonardo Da Vinci said, “All our knowledge has its origins in our perceptions”. Mark Twain said, “Of all the things I’ve lost, I miss my mind the most”. Twain also said, “Be careful about reading health books. You might die of a misprint”.
