I found this article about how drowning doesn’t look like drowning fascinating. Mostly because my brother almost drowned right in front of a life guard when we were little. Literally 2 feet in front of a lifeguard. Who was sitting at ground-level. Watching my brother do a fantastic impression of someone treading water.
What the life guard wasn’t noticing was that he was pushing the water right into his open mouth. Which was at water level, not above it.
The first clue for me was that my brother wasn’t supposed to be in the damn pool by himself. If I hadn’t known that, I might not have really seen what was going on either. The upshot was he didn’t die. Another benefit was that since I’m the one who jumped in and saved his life, I didn’t feel as bad when we discovered his horribly deviated septum was from that time I accidentally kicked him in the face.
