Read books and get the knowledge out of it
Without books,
There is no record of humans ever existing
When all of us die
You have a day to destiny
You can detect what would happen in the future
How cool is that
Historians keep records of the past
Without them, we would never know 
the lives of people in the past
Scientists discover new cures for diseases
Without them many of us would die 
Mathematicians calculate to know results
They all of these through books
Without books we would'nt survive in the world
Knowledge is power
With the knowledge of these people,
They save the world
So they are our Heroes
