This song should be pretty easy to pick up. So heres the way I think it goes (note: I
added a few things, so maby it is a different version than the other chords I found here)

[Intro]

Growing older

[Play slower]

My mind is rac

w I'm

quit.

            
And I'm so con

Sometimes I wa

 But if all th

            
at I can do is

        
 just sit and
            
watch time go,

              
 then I'll hav
