1.   And the sweat rolled down their faces in rivers.

2.   Is that sweat rolling down my shins?

3.   It gets hot in this part of Louisiana, even in February, and the sweat rolled off the marchers.

4.   Sweat rolled down their blank faces as slowly as the drum purred the rhythm that comes with death in the line of duty.

5.   Sweat rolls.

6.   The sweat rolls freely after yet another lengthy workout on this hot, muggy afternoon in August.

7.   The sweat was rolling into my eyes.

8.   Sweat rolls down her face, protected against mine explosions by only a helmet.
