Back in the days of J-valves running out of air happened a lot. :( Bumping the J-valve down on the down line or wreck made for an exciting dive and nobody I knew got "over expansion injury" :)
It’s amazing coming up from 90’ how much air keeps bubbling out of your mouth! After that you become anal checking the rod to make sure the valve is in the correct position all during the dive :)
