Once upon a time
there was no time...
we discovered concept of time
it's behavior not universal
Coz

at the age of 6th to 12th
can feel the time
especially
in Maths class..

Being 16 to 35 yrs
time flies and...

at the age of 60 plus
We slowly hate the concept of time
coz it never moves.....

If a concept of time
changes based on age...
It's not a concept
then...
What should we call???
