P.S.. I'm an Engineer..!!!

I was suffering from stomach ache this evening.. and then this awesome doubt struck me..!! :P

According to me, sensors can sense, processors can process and motors can run..

but motors can't sense, sensors can't process and processors can't run..

Similarly, sensor organs can sense, muscles can move, heart can pump blood and brain can think..

and not the other way...

YES.....!!!!!!!???????

All the science and biology lessons taught me that the human body has only five sensors...

1.Eyes

2.Ears

3.Nose

4.Tongue

5.Skin

If i pinch you, your skin senses it.. and thus u feel pain.. ;)

But the stomach aint a sensor.. ;)

THEN HOW ON EARTH AM I ABLE TO SENSE PAIN IN MY STOMACH...

WHAT DAMN SENSOR IS PRESENT INSIDE...????

P.S.. I'm an Engineer...!!!
