Yep. Used to be a lifeguard. Preformed CPR on three different people. Also stopped once at a car accident. Driver was bleeding profusely from the leg. I used my shirt to help stop the bleeding. Not sure if she would have died, but she was bleeding alot.
I saw a car go through a barrier and land in a canal about 20 ft deep. I turned my 1970 Camaro around to dive in and save him. When I arrived, he was swimming up from the bottom. Headlights and taillights still on under water. He was drunk and bout 18. He asked me to drive him home.Told him sorry cant do it, as the police arrived.
My cousins and I were swimming and my little cousin couldn't swim so she had to stay in the shallow end. She got one of those boogie board things and jumped in the deep end and ended up falling off. She started going under and I grabbed her and held her head up and swam her over to the edge of the pool. I bet someone else could have helped her if I wasn't there but I was the first one to realize the danger. It was really scary.
