Anyone know that song '100 years' by Five for Fighting.....???

My FH mentioned having it for the wedding video for the growing up pictures, I'm not sure if it fits, granted it's a really good song, but I'm not too sure what it means
link to song (go to bottom to listen to samples)
here are the lyrics:
I'm 15 for a moment
Caught in between 10 and 20
And I'm just dreaming
Counting the ways to where you are
I'm 22 for a moment
She feels better than ever
And we're on fire
Making our way back from Mars
15… there's still time for you
Time to buy and time to lose
15…there's never a wish better than this
When you only got 100 years to live…
I'm 33 for a moment
Still the man but you see I'm a they
A kid on the way
A family on my mind
I'm 45 for a moment
The sea is high
And I'm heading into a crisis
Chasing the years of my life
15… there's still time for you
Time to buy and time to lose yourself
Within a morning star
15… I'm all right with you
15… there's never a wish better than this
When you only got 100 years to live…
Half time goes by
Suddenly you’re wise
Another blink of an eye
67 is gone
The sun is getting high
We're moving on...
I'm 99 for a moment
Dying for just another moment
And I'm just dreaming
Counting the ways to where you are
15… there's still time for you
22… I feel her too
33… you’re on your way
Every Day's a new Day
15… there's still time for you
Time to buy and time to choose
Hey 15… there's never a wish better than this
When you only got 100 years to live

nobody???

i never heard it before
but i like it
kinda like DMB style song

the song is about remmebering the pasat and also looking ahead at the future / yet at the same time putting yourself in the position of being much older and thinking about how you are goona look back on life

so i think that would be a great song for the video

just think when you guys are watching the tape when you have your first kid ,or your first grand child or your 50 th anniverery
it will bring it to life

thats what i think
