Welcome to the club, now that you have the lives of small children who constantly think of you as a "jerkface" "doodoohead" in your hands, remember not to throw them in the water.
Also on a more serious note, you can become a lifeguard online now? I had to go through an entire year of training in stuff IRL. I didn't even know it was possible to teach a physical job/skill online. That would be like taking Gym class on the internet; which would admittedly be more interesting for sure lol.
