100 Years

I think this is a great song. Obviously it can be interpeted many diffrent ways. What I got out of it is the life of a love relationship. I get this by looking at the the song, and not just the chorus (which many have the bad habit of doing). My reasoning is like when he says he is 15 he is dreaming wondering where his love is, nearly all 15 year olds haven't met the one they are going to be with forever. At 22 they are on fire making their way back from Mars, at 22 you are in the state of meeting each other and are head over heels and giddy, much like fly through space. At 33 you are married and are still a single person, yet considered a "they" as in he and his wife. A kid on the way and a family on his mind, self-explanitory. At 45 the sea is high, things are getting rough, heading into a crisis, mid life crisis, chasing the years of my life, wondering where all the years have gone. At 99 he is dreaming counting the ways to where you are, what I got was his wife has passed and as his own death nears he wonders where she went and he is going. That is just my intrepetation.
