A ton of prep work has gone into this trip: flights, trains, lodging, activities, and most notably scuba.
Tomorrow night I have my next to last scuba class before we head to open water this weekend. Scuba class teaches all the skills to prepare you for the worst under water. The worst of the worst being running out of oxygen. I have been breathing oxygen longer than I care to remember and I have always had plenty of it. Last class I found myself without oxygen for the first time.
The instructor cut my oxygen to teach us how it feels. Imagine trying to breathe in and feeling your entire chest clinch because it cant expand. Even when you know its going to happen and extra oxygen is a few feet away, you can't help but freak just a little, ok alot. I think its gotta be instinct for your body to start punching your brain.
Other skills are things like losing your mask, losing your regulator, gaining and losing buoyancy, etc. However I think the big skill is to not lose your mind when something goes wrong. Once you start to panic its game over.
In honor of people doing things I cant even imagine here is a video of some free divers. Mind you they are holding their breath and have no oxygen. I freaked after 3 seconds this is 3 minutes 100 feet under water.
