Croup is a condition that causes a swelling of the voice box (larynx) and windpipe (trachea). The swelling causes the airway below the vocal cords to become narrow and makes breathing noisy and difficult. It is most commonly caused by an infection.
A golf slice is a shot that usually ends up far to the right of your intended target. For some players this shot can curve 30 or 40 yards off line. Excessive left to right hand spin on the golf ball causes a golf slice to occur. A small amount of left to right spin on the golf ball will cause what is called a fade.
Golfers will often employ a strong grip on their clubs because it helps them hit the ball squarely with the clubface. When using a strong grip, you lower the risk of hitting the ball with an open face, which results in a slice. When the clubface is square, or closed, upon impact, you hit the ball straight and for a greater distance.
