It was a sunny afternoon at the park, and a little girl was laughing happily as she pumped her legs high into the air on a wooden swing. Suddenly, the rusty metal chain snapped with a loud crack, launching her straight into the air. Hearing her scream, her older brother didn’t hesitate for a single second—he dove completely flat through the air like a superhero, catching her tightly against his chest as they slammed into the concrete. Their loyal golden retriever barked wildly, and their mother ran out of the house screaming their names. Miraculously, because of her brother’s lightning-fast reflexes, the little girl escaped without a single scratch.
