Because

The times you've had
Won't come again forevermore
And after all is said and done
There's nothing there
You always wind up where you began
You never give a thought to tomorrow
Why where you going now
Show where you've been to
When where you coming from
Where what it show you
If what u doing now
What where'd it leave you
Why where are you going now
Because
I see you are alive and well and looking good
But your road is winding to the end
So be prepared!
And what you get is what you give
Don't think that anything means anything
