In order to renovate the house, someone in Japan tear open the wall. Japanese houses normally have a hollow space between the wooden walls.
When tearing down the walls, he found that there was a lizard stuck there because a nail from outside hammered into one of its feet. He sees this, feels pity and at the same time curious, as when he checked the nail, it was nailed 10 years ago when house was first built. What happened..?
The lizard has survived in such position for 10 years!!! In a dark wall partition for 10 years without moving, it is impossible and mind boggling. Then he wondered, how this lizard survived for 10 years without moving a single step - since its feet was nailed!
So he stopped his work and observed the lizard, what has it been doing and what it has been eating? Later, don't know from where appears another lizard, with food in its mouth... AHHH! He was stunned and touched deeply. For the lizard that was stuck by nail, another lizard has been feeding it for the past 10 years.
