Let us talk some silly matters

A vast number of things are found in this world . But we didn't offer any simple attempt as yet to know about it and it's specialities which distinct them from each other.
For instance, if u have a look upon the snake, when it follows us, if we receive a zig-zag method troughout our running, it would try to imitate us.That makes it far away from us .So we can escape easily from it .
If we throw the cat from the height, it will touch the earth with it's four leg however we try...
Take a fresh mango without worm , keep it in a wholeless box or cover for some days ,let it to decade.... and look it after some days ..you would be amazed that from where did it come..!!!
And so such other things that we can't touch our elbow with our tongue..
We can't think two things simultaneously

Nobody could read all books that published till now and so on..
We can't fold a paper more than seven times ....
Any obstacles we can remove but water and fire...
