Does turning OFF the headlights of the car, save the fuel ???

Technically      YES   !!!

Headlights draw electricity from the battery, which is recharged by the alternator.

Alternator is powered by engine which runs using fuel  !!!!

But the amount of fuel saved is very small....

Its better to use LEDs instead of halogens for headlights.

LED bulbs use incredibly low power.  Turning these OFF virtually saves zero fuel.

More importantly,

KEEP THE HEADLIGHTS ON FOR SAFETY THAN FUEL SAVING    !!!!

Why do humans get dizzy ??

 Dizziness happens when brain gets confused signals about where the body is  !!!

It also happens when body is not getting enough oxygen or blood.

1.   When balance system gets mixed signals 

                    We have fluid filled canals inside ear which tells the brain whether the head is rotating or not.

                    Eyes track where the horizon is and what is moving around.

                    Nerves in muscles and joints tell whether body is sitting, leaning or standing.

When these 3 disagree with each other, we get dizziness  !!!

 Example  :  Reading in moving car .

Let's see what happens.   

        

Eyes say, We are stationary.

Inner ear  :  We are turning and accelerating   !!!

Body muscles   :  We feel the motion 

Brain  :  ERROR   !!!!

Other reasons are   ----

1.  Blood flow drops to brain 

2.  Direct hit to inner ear /  brain 

3.  Anxiety and fatigue 

Most dizziness is brief and harmless......

It is worth checking if  dizziness is frequent, comes with hearing loss, severe headache or fainting.
