TIME OUT
"Chasing Time" "Time is money"
In the indefinite future, and for some unknown reason (certainly to avoid overcrowding), time became the sole currency of the man, whose life ends at 25 years old. His time is money it will need to win if he wants to live longer. Why not forever .. But time is spent also like money. For example, if he should be given 4 minutes to give a coffee, it appears on the forearm as a place of a watch. Poor neighborhoods are filled with corpses, human beings who could not get more time and deaths are numerous. However, districts have no worries, and most have become almost immortal. They have enough time to live in comfort and safety.
