YOUR brain uses 20 per cent of the oxygen that enters your bloodstream.

The brain only makes up about two per cent of our body mass, yet consumes more oxygen than any other organ in the body, making it extremely susceptible to damage related to oxygen deprivation. So breathe deep to keep your brain happy and swimming in oxygenated cells.

Nerve impulses to and from the brain travel as fast as 170 miles per hour!

The brain operates on the same amount of power as a 10-watt light bulb and it generates as much energy as a small light bulb even when you’re sleeping.

So the cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark!
