I worked as a lifeguard in high school and had to save a kid once.

I didn't even think he was having trouble until one of the counselors yelled, "DIMINOTEN!" He was taking a swim test and looked just like all the other kids, except he wasn't going anywhere.

Being a lifeguard is a silly job. 99.999% of the time you're doing nothing but sitting in a chair, trying not to fall asleep. It's that ONE time when you need to be paying attention that's critical and matters absolutely.
