When Air Becomes Breath

A close friend recently told me about a book titled "When Breath Becomes Air" written by a neurosurgeon who was diagnosed with Stage IV lung cancer.

My first thought was that the order of words in the title should be reversed to "When Air Becomes Breath".  (Or maybe more significantly could be modified to "When Air Became Breath".)

It is interesting that both ideas suggested by these titles can be pretty thought provoking.
