"Freedom's just another word for nothin' left to lose, And nothin' ain't worth nothin' but it's free..." - Me and Bobby McGee, Kris Kristofferson
So it was depicted as Janis Joplin wailed out these bluesy words to this despondent tune back in 1969 at the height of the Vietnam War. I recall it well. But is it true? Is freedom really "nothing left to lose, and nothin' ain't worth nothin' but it's free?"
