Man from the South

In this story, a young soldier is persuaded into participating in a bet that if lost, could cost him his pinky finger. The boy talks about how he really doesn't need his pinky finger anyway, taking for granted what all his pinky does for him. Without the use of his pinky, he would lose about half of his grip strength. This young man's daily activities as a soldier would be greatly impacted if this were to happen. His ability to operate firearms, technology, and other various important things would be dramatically impaired. He would not be as accurate with his shots fired in the field which would be detrimental to his career, his life, and the lives of his comrades. 

At the end of this story, we get some insight on the life of the rich, betting man's wife. Throughout all of her betting against her husband, she is now left with only a thumb and a finger on one hand. Only having two fingers means the wife would have a lot of difficulty with daily activities such as brushing her hair or buttoning up her shirt. Something that could be done to help with hair brushing is to place a Velcro strip on the back of the brush that can stick to a Velcro strap placed around the hand. With this, the lady will not have to work as much to grip and hold the brush (since we know how much grip strength is lost without the pinky). Velcro can also be used to modify dressing for her as well. You could put Velcro spots under the buttons of a shirt so that she can just Velcro her buttons down instead of actually manipulating the button into the hole.
