Understand lyrics

I might not know the reason
For the changing of the season
But I know how I feel about this
When it comes to birds and the bees
And chemistry baby
You and me, we're a perfect fit
In a world where anything goes
Out of control girl it's good to know
There's a heart of gold and someone to hold
Back home waiting on me

There's a lotta things I can't figure out
Like how a 737 gets of the ground
When a prayer goes up and answer comes down
What you're doing with me right here right now
Why am I such a lucky man?
Head on my shoulder, hand in my hand
It'll always be a mystery
Yeah there's just some things
I don't need to understand

When you're rolling on this crazy ride
I don't know how the mind decides
Which moments become memories
You're gonna keep for life
Come on baby whatcha say
We make some more tonight
There's a lotta things I can't figure out
Like how a 737 gets of the ground
When a prayer goes up and answer comes down
What you're doing with me right here right now
Why am I such a lucky man?
Head on my shoulder, hand in my hand
It'll always be a mystery
Yeah there's just some things
I don't need to understand

How the moon causes oceans to rise
Or where the time goes when it flies

There's a lotta things I can't figure out
Like how a 737 gets of the ground
When a prayer goes up and answer comes down
What you're doing with me right here right now
Why am I such a lucky man?
Head on my shoulder, hand in my hand
It'll always be a mystery
Yeah there's just some things
I don't need to understand
