Reaction Time

     Reaction time is the way you react and how fast you react. 
When i'm playing soccer and they pass me the ball my reaction have to be fast , because if i don't react fast somebody  else is going to take it away from me, you do not want that to happen. When you are drinking very hot coffee and is about to fall you better react fast to that because that really burns and you have to react smartly because if you react stupidly you might spill some more. When you are distracted and someone calls your name and you look and a baseball ball is coming directly to your face you have to react quickly if you don't want the ball to hit you.
