Now he was beginning to have the waft of an old man who hadn't bathed for several days.
The meaning of the sentence is absolutely clear to me, since the second part of the sentence explains the meaning.
But I have only a rough perception what the exact meaning of a waft of is.
I found this explanation of waft:
To cause to go gently and smoothly through the air or over water.
And to waft means:
to move, or make something move, gently through the air
But at this point I stuck and I fail to figure out the exact meaning. It sounds like it means the smell itself in an foul-smelling way, but then it would be rather uncouth.
Am I headed in the right direction or has a waft of a deeper meaning?
