So I stick a Mars bar in my left ear and that will light up, right?

Why yes, yes it will !!

That's got me thinking.........OUCH! That hurts.

If I stick a 20 watt bulb in my left ear, will it light up?

Why yes, yes it will !!

Blimey, with that and a fish up your bum, you've got pretty much all options covered....

I was just wondering if you could EVER stop thinking? When I try to do it I always notice myself holding my breath, maybe my brain stopped thinking for a second and turned many/every thing(s) off. You should try and stop thinking. Not that it probably helps burn many calories...

If ewe do stop thinking , what then kick starts the ' start thinking ' ?

The Mars bar in your ear and the goldfish up your bum.

The brain is always active, so you cannot stop yourself from thinking. When you are doing something, it is thinking about what you are doing and what you are going to do next. When you are doing nothing, it is thinking of what to do or just day dreaming and when asleep, it gets the chance to run riot with thinking about what IT wants to think about.

The brain accounts for about 20-25% of the energy burned in the body (less if your initials are GW and your surname begins with a B). This means the brain runs at about 35W.

Thinking does not significantly increase brain energy consumption but it does lead to a redistribution of energy use within the brain whereby the region of the brain responsible for handling the task being undertaken increases its activity (increasing energy consumption) whilst other (now less active) regions reduce their activity and hence energy expenditure.

Is this why high stress can cause health problems? The person is always thinking hard about something so energy is distributed to the area of the brain that this uses for too long, depriving other areas?
