It’s November, the temperature is -5 degrees, and it’s snowing. June looks outside and decides to shovel her driveway.  Her driveway is not very big and she feels can get it done before her guests arrive. About halfway through shoveling the driveway, June begins to feel a little nauseous.  She tries to finish but the more she continues the more nauseous she gets. Now, she is beginning to get extremely tired.
