Funny, I started watching this thinking the same thing Destin did.... "I'm an experienced diver... I'm super comfortable being underwater, even upside down and in enclosed spaces"

and then they talked about letting your sinuses flood... and my brain went "nope, not having that".

*quality video about not panicing in a tough situation.

As someone who doesn't know how to swim very well (my feet and hips sink and I basically make big splashes across the water in an huge effort to avoid sinking) I'd be super panicked in this situation.

If you keep air in your lungs and avoid paniced movements your body will start to float up on it's own. While on the surface move your legs and feet as if you were peddling a bicycle.

That should keep you from panicking unless you see sharks, so keep your eyes closed.
