I’m in serious trouble. I’m in my full rubber vintage wetsuit with hood, my weight belt, flippers, and vintage oval mask. I’m in the tub and breathing from the regulator attached to my air tank. But I am tied up in this heavy steel chain. Not only is the chain tight around me so that I can’t move my arms, it is so heavy that I can’t even lean up. I don’t know much air is left in my tank, but once it’s gone, I’ll be a goner! See my panicked face and eyes behind my mask as my smoky lungs suck down the air too fast.
