That's the exact reason why I would never scuba dive because I'm always worried I might find a dead body deep under sea.
I never thought about what I might see under water during the polar plunge because it's a quick dip in and out. But I'm glad there was no discussion here before hand. With your shark and @leaky20's giant squid, I'm sure you guys would have put me off doing it 🤣🤣🤣
