You are young and life is long and there is time to kill today
And then one day you find ten years have got behind you
No one told you when to run, you missed the starting gun
And you run and you run to catch up with the sun but it's sinking
Racing around to come up behind you again
The sun is the same in a relative way but you're older
Shorter of breath and one day closer to death
- Pink Floyd, "Time"
