Lengths of time seems shorter, insignificant when you compare them against a lifetime -- as a lady philosopher once told me, this is called the "single star against the night sky" effect.
But taking a period of time on its own merits, weighing its consequences, and the amount achieved (or lost) within it, even a second could feel like forever; with the Olympics going on now, and all those athletes who are losing races by half-seconds, you would probably find many people to attest to this fact.
If a second feels like forever, then imagine what 15 months feels like. More than forever? Or the beginning of forever?
