Blowin' In The Wind

I was doing some house work today and figured I would listen to Bob Dylan's second album The Freewheelin' Bob Dylan. The first song is Blowin' in the Wind. I must have heard this song well over 100 times at this point in my life, but as I have grown older the song feels more important than ever. The first concert I ever attended was seeing Bob Dylan at the age of 13. He would do a free concert every year at Conneaut Lake in Western Pennsylvania. 
 

Yes, how many years can some people exist
Before they’re allowed to be free?
