"I don't have time. I don't have time to worry about how it happened. It is what it is. We're genetically engineered to stop aging at 25. The trouble is, we live only one more year, unless we can get more time. Time is now the currency. We earn it and spend it. The rich can live forever. And the rest of us? I just want to wake up with more time on my hands than hours in the day" -- Will Salas (Justin Timberlake) In Time
These are the opening lines to the film In Time where time literally is money. At age 25 you stop aging, but you only have one year left to live. You can work for more time, trade time, steal time and fight for time, no matter what you spend time.
