This story reminds me of playing the board game "Deep Sea Adventure" ( https://boardgamegeek.com/boardgame/169654/deep-sea-adventure https://boardgamegeek.com/boardgame/169654/deep-sea-adventur... ) with some friends. In this game you try to get as much treasure as you can from the sea bottom floor. At the same time you share your oxygen supply with your competitors. We managed to run out of air three times in a row! The final round was particularly amusing: When the players noticed that (only) one player had a chance of making it back to the surface, they made sure to use up the shared oxygen supply since they were doomed anyway. Fun game, give it a try. Also quite educational, just as this excellent short story.
