You're going to gain a lot of respect for lifeguards after this video.
I had to watch it twice to really see what happened, and I'm honestly shocked by how fast the lifeguard's response time was.
The kid fell off the inflatable pool donut and under three seconds later the lifeguard was in the water and racing to his spot.
The video was posted to the Lifeguard Rescue YouTube channel, an account devoted to giving lifeguards real-life examples of pool rescues.
Stay safe this summer, kids.
